Acoustics in recording studios

Acoustics in recording studios

Recording studios need over quiet to catch the pitch and tone of sound warmly. Absorbers which are materials with a high value of sound absorption coefficient. However, adding these materials randomly is not a good effective solution because every situation needs its own solution. Engineers calculate the exact amount and place of these panels. This step follows measurements and studying the characteristics below:

• Reflected Sound – Reverberation

When a sound source ceases in space, the sound waves will continue to reflect off the hard wall, floor and ceiling surfaces until it loses enough energy and dies out. The prolongation of the reflected sound is known as reverberation. Reverberation Time (RT) is the number of seconds it takes for the reverberant sound energy to die down to one millionth (or 60dB) of its original value from the instant that the sound signal ceases.

Reverberation is dependent only on the volume of a space and the acoustically absorptive quality of the room’s finishes. Hard surfaced rooms will have a longer reverberation time than rooms finished with sound absorbing materials.

When a sound wave travels outward in all directions and encounters an obstacle such as a wall, floor or ceiling surface the direction of the sound will be changed or reflected. The direction of travel of the reflected sound will be at the same angle as the original sound striking the surface.

The immediate effect of multiple reflections is an increase in the sound intensity caused by the reflections. A listener will hear the direct sound arriving at the ear along with all of the multiple reflections. Thus the combined loudness of the direct sound and the reflected sound will be greater than the direct sound alone.

• Noise Reduction Coefficient (NRC)

An NRC of 0 indicates perfect reflection; an NRC of 1 indicates perfect absorption.

It is the arithmetic average, rounded to the nearest multiple of 0.05, of the absorption coefficients for a specific material and mounting condition determined at the one octave band centre frequencies of 250, 500, 1000 and 2000 Hz.

Absorption coefficients used to calculate NRC are commonly determined in reverberation rooms of qualified acoustical laboratory test facilities.

NRC is most commonly used to rate general acoustical properties of acoustic ceiling tiles, baffles, and banners, office screens, and acoustic wall panels.

• Frequency of Sound used in the studio:

Sound is the quickly varying pressure wave traveling through a medium. When sound travels through air, the atmospheric pressure varies periodically. The number of pressure variations per second is called the frequency of sound and is measured in Hertz (Hz) which is defined as cycles per second.

The higher the frequency, the more high-pitched a sound is perceived. The sounds produced by drums have much lower frequencies than those produced by a whistle.

The generally accepted standard range of audible frequencies for humans is 20 to 20,000 Hz.

The adult male voice has a frequency range of fundamental frequencies from 85Hz to 180Hz.

The adult female voice has a frequency range of fundamental frequencies from 165Hz to 255Hz.

The Frequencies of Music are much higher reaches thousands of Hz.

Acoustic doors

Acoustic doors

Quality of life requires increasingly strict standards; to protect people and/or their environment. One of the problems faced is sounded hustle. That will be annoying and produce noise most times so sound insulation is applied to maximize the acoustic performance.

In our buildings, while walls block sound waves noise is basically transmitted through doors.

If doors do not meet the same acoustical requirements as the rest of the room, then the sound will easily pass through it to adjoining spaces. When fitted with the right door and sealing systems, the noise will be contained and controlled.

An acoustic door is a solid, heavily framed door which most often includes seals around its edges and has insulated construction to reduce noise and vibrations from passing through its surface. Depending on the application and the design. There are many types and grades of acoustic door available for assorted applications and industries.

These doors can have a variety of purposes, such as enabling confidential discussions to be held inside a room without the risk of those outside overhearing and allowing noisy activities to take place, such as music rehearsals, without nearby rooms and areas of the building being disturbed. Music studios are one environment which typically makes use of acoustic doors. When audio is being recorded it is important that external noises do not interfere with the sound being captured. The control room with producers and engineers inside it needs to be isolated, and each room in the studio must contain its own noise levels successfully to avoid disturbing those in neighbouring rooms. Sound insulation in these settings is not an optional extra, it is absolutely essential for the functionality of the building. In the audio recording industry, the acoustic door serves a special purpose since unwanted noise needs to be avoided in a successful recording session. In a recording studio you may have several rooms or booths that are designed for specific tasks. The studio control room has an acoustic door so the engineer and producer can be isolated from the additional rooms and parts of the studio while allowing these individuals to travel between locations. Sometimes these doors will be transparent containing multi-pane glass panels in the center so that individuals on each side can see each other easily.

Acoustic doors are vital to properly insulate the sounds inside a room. The combination of the doors’ solid build, their edge seals and the frame, along with the insulated engineering within the body of the door, all contribute to a significant reduction in the vibrations and sound that pass through it. Sometimes an acoustic door is solid steel or wood with an insulated core to achieve maximum quiet when transparency is not necessary. A door of this style is quite often used in an examination room at a doctor’s office where a conversation between the doctor and patient requires total privacy.

Another logical home for an acoustic door could be a conference room at a corporate office where information concerning product development, human resources or business strategy would be discussed. Counselling centres, police station questioning rooms, and testing facilities or anywhere where privacy and confidentiality are essential, can be included as an application for this type of door. Another work environment where acoustic doors are increasingly commonly used are medical or healthcare premises. When patients talk in confidence to their doctor, nurse or counsellor they have an expectation of privacy and discretion. Compromising this, and their trust in the service or staff they are working with, by having doors which allow sound to penetrate through could have a detrimental impact on their relationship with their physician or healthcare worker, so if they can overhear a doctor’s discussion with another patient through the door, they will have no faith that their own personal conversations and concerns are being kept private.

Another scenario where acoustic doors can provide considerable benefit is for corporations or businesses who have meetings where sensitive information is discussed. This might include meetings about staffing and human resources, product development, grievance procedures or business strategy; all of which could have a negative effect if overheard. Even if just a snippet leaks out of the room, assumptions can be made and confidences broken, so mitigating against this risk by installing acoustic doors can make situations easier to manage, and keep sensitive information to within the appropriate group of people.

Factories or businesses which house heavy machinery are also prime candidates for benefiting from an acoustic door. The business owners can promote positive aural health by limiting loud noises to one part of the premises where adequate hearing protection is used. Preventing this noise from leaking to other sections of the building will make it a more pleasant, as well as safer, place for employees and managers to be.

Production departments or facilities that contain heavy machinery, tooling or motorized activity usually have acoustical doors throughout the location to keep hazardous sound levels out of populated areas. A large manufacturing plant may use an acoustic door to establish privacy and protection for managers required to monitor productivity on the main floor. A newspaper will use acoustic doors and panels to dampen the sound of large printing presses while allowing a passageway for pressmen and technicians to maintain and operate the machinery.

Logically, any facility where sound needs to be separated from people, places or things to ensure safety, privacy, or productivity and still provide a method of passage between two or more locations, will need a door of this type. A good look around our individual environments should help us notice with more clarity a number of uses for the acoustic door.

Soundproof acoustic doors which commonly made from wood are an ideal cost-effective Acoustima® acoustic panel by Seatup Turkey® solution because it does not need much coating but absorbs sound by its self moreover, they are suitable for a wide variety of applications in any room, office or hall.

They are tested to ISO standards and achieve an average level of sound reductions up to 55dB.   according to durability and sound transmission loss, other requirements may also apply, such as fire resistance and high thermal insulation.

Acoustic doors are designed to reduce the escape of noise and vibrations from one room to another. With a multitude of potential uses in a wide variety of industries and sectors, these doors are available in different decibel ratings to cater for the needs and requirements of individual circumstances.

Acoustima® acoustic panel by Seatup Turkey® also have a selection of door accessories which help in improving sound quality too. Whether it’s for new construction or retrofit, we can help!

Acoustics in public buildings

Public buildings are any type of building that is accessible to the public and is funded from public sources. All types of government offices are considered public buildings. Public buildings generally serve the purpose of providing a service to the public. Many of these services are provided free to residents. This list includes public schools, libraries, courthouses and post offices. While it has so many crowds inside it, clearly it has an acoustic problem. Imagine students shouting, clients talking, and employees sounds.

The improvement on the human quality of life and the continuous growth in population in developing and developed societies, have exacerbated the environmental and financial issues. Some of these problems are noise and the different types of human an industrial waste. Many natural products have been recently developed and tested for acoustic applications. Sound-absorbing materials absorb most of the sound energy striking them and reflect very little. Therefore, sound-absorbing materials have been found to be very useful for the control of room noise. In this article, sound absorption technology as an effective noise reduction technology building using sustainable acoustic absorbers, will be discussed. Many public housing sites are subject to severe noise impact from various sources.

Let us focus on the most common public buildings and Acoustics in public buildings:

Schools

Another type of public building is schools. Public schools exist in nearly every town. These schools are for grades kindergarten through 12th grade. As you know a big challenge will face this ambiance.

Courthouses

Courthouses are a common public building. The public utilizes a courthouse for many different purposes. Clarify and quality of sound is preferable. Trials are held at courthouses, important documents are retrieved and most health departments are located within a courthouse.

Post Offices

A post office is a government-owned public building. The post office performs many different mail functions including receiving it, handling it and delivering it.

Libraries

They are an essential part of communities and offer many types of services. People visit libraries for many purposes including checking out books, magazines, publications, music, and movies. The public can also visit a library to access the Internet, make photocopies and to join different types of programs. These kinds of public buildings need much more quiet and relax, so acoustic treatments and solutions must be considered.

These problems need an acoustical solution to reduce noise and increase the quality of sound reaching the human ears.

To mention Sound Absorbing Materials which are used in acoustic panels Acoustima® acoustic panel by Seatup Turkey®:

Porous materials obtained from synthetic fibers, such as mineral wool or glass wool, are commonly used for thermal insulation and sound absorption, because of their high performance and low cost. Their diffuse-field sound absorption coefficient is very high at midhigh frequencies. Viscous losses convert acoustic energy into heat as sound waves travel through the interconnected pores (or fibers) of the material. Because motion of the air through the porous material is necessary to dissipate acoustical energy, a material tends to be ineffective when placed close to a rigid boundary. Effectiveness of absorption is directly related to the thickness of the material; absorbers are most effective when their thickness is between one-fourth and one half the wavelength of the sound, with the maximum performance where the thickness is one-fourth the wavelength. This means that sound absorbers do a very good job at high frequencies, which have short wavelengths.

A majority of sustainable materials for noise control can be divided into three main categories:

– Natural materials;

– recycled materials;

– Mixed and composited materials.

Acoustima® acoustic panel by Seatup Turkey® offers powerful solutions which can be used in Acoustics in public buildings at a reasonable cost in response to all the needs in the matter of soundproofing (preventive or curative) by the means of ergonomic equipment (standard or tailor made) for which the quality of design and of execution meets the highest level of requirement in this area for an efficient fight against noise in the context of compliance with legislation on noise at work (or of improvement of working conditions) or of compliance to the regulation in terms of acoustic comfort in buildings.

Acoustic solution for airports

No one can ignore or refuse the fact that airports have a very genuine noise pollution problem. When we focus so much on noise we awake about hearing impairment, noise-induced hearing loss, tinnitus, stress, increased risk of accidents, and so many physical and psychological health problems.  

In addition to this, especially in airports, there is a need to quiet to be attention for calls and notes they broadcast.

So that limiting exposure to loud noises (Acoustic solution for airports) is very important.

Aircraft noise pollution is a harmful noise effect produced by any aircraft or its components during the various phases of a flight. Sound production is divided into three categories:

• Mechanical noise—rotation of the engine parts, most noticeable when fan blades reach supersonic speeds.
• Aerodynamic noise—from the airflow around the surfaces of the aircraft, especially when flying low at high speeds.
• Noise from aircraft systems—cockpit and cabin pressurization and conditioning systems, and Auxiliary Power units.

sound level near the airfields generated during noisy aircraft ground operations. In the vicinity of airports, noise is affected not only by landing and taking off of aircraft but also by noisy aircraft ground operations. The resultant sound level nearby airports is affected also by certain ground operations which are related to taxiing of an aircraft from stand or sleeve to the beginning of the runway, and after landing, from the runway to the stand. Noise levels emitted by those operations are very harmful to the ground crews.

Acoustic solution for airports is to reduce the level of noise by using sound absorption panel.

The function of absorptive materials is to transform impinging acoustic energy into heat. Because the energy contained in sound waves is normally very small, the quantity of heat generated is also small.
