Acoustics in swimming pool

Swimming Pools have one of the most difficult of environments to treat acoustically.  With hard tiled surfaces surrounding the pool mixed with the sound of people swimming, playing and shouting the noise can reach extreme levels.  Instructors of swimming lessons would find teaching very difficult alongside the poor swimming pool acoustics and the serious problem existed of misunderstanding the public address system announcements and instructions in the event of an emergency. Swimming pools & leisure centres should provide an acoustic environment that allows people to enjoy their leisure time in peace, within a safe environment regarding humidity moderator.

Controlling Swimming Pool Acoustics

The goal with your soundproofing treatment is to improve the sound quality by lowering your level of ambient echo. By reducing your background noise, you raise greater clarity to original sound and produce a more user-friendly swimming environment.   This is accomplished by introducing a set of sound panels for swimming pool acoustics that can effectively combine to capture and convert the unwanted echoes out of your room and deliver back the sound values you are seeking. Acoustic baffles can be wall or ceiling mounted inside your space.

A Noise Reduction Coefficient is an average rating of how much sound an acoustic product can absorb. (How much quieter a product can make your space.) Like a sponge absorbs water, an acoustic product absorbs sound and the NRC tells us just how much sound those products can soak up.

The Scale

NRC ratings range from 0 to 1. An NRC of 0 means that the product absorbs no sound. An NRC of 1 means that the product absorbs all sound. The higher the NRC, the better the product is at soaking up sound

The thickness and density of a product are two factors in calculating a Noise Reduction Coefficient. An acoustic product with a .95 NRC rating means that 95% of sound in the space is absorbed, while the other 5% is reflected.

The acoustic panels with insulation materials which used within the construction structure are the ideal solution for absorbing sound in areas with large volumes such as swimming pools.

Acoustics in sports halls

Indoor sports halls and gymnasia differ substantially from other secondary rooms in that they are very much larger spaces intended in general for teaching groups of active students. As a result, they have a dramatically different acoustic environment. Sports halls are rated as the most difficult learning space to hear in.   Although design criteria for the acoustics of indoor sports halls and gymnasia are part of current building regulations, in practice it has been difficult for designers to achieve these standards. Sports Facilities such as sports halls and gymnasiums are large open spaces built to withstand years of use for a variety of sports. They are built with hard wall, floor and ceiling surfaces making them particularly poor acoustically. These spaces are often used for a variety of activities making their acoustic performance important in order to facilitate clear communication and provide an enjoyable atmosphere whether the activity is a school assembly or one of the many sports which are carried out in these environments.

Sports hall acoustics are typically reverberant due to a combination of large areas of hard block walls, corrugated steel ceilings and wooden floors along with high ceilings.  To control a sports halls acoustics, a large amount of acoustically absorptive material has to be applied around the hall.  A spray-on material has a distinct advantage over acoustic panels in this situation.

An important term we should talk about here is ‘’ reverberation time’’ Reverberation time: is the time required for the sound to “fade away” or decay in a closed space. Sound in a room will repeatedly bounce off surfaces such as the floor, walls, ceiling, windows or tables.

When these reflections mix, a phenomeon known as reverberation is created. Reverberation reduces when the reflections hit surfaces that can absorb sound such as curtains, chairs and even people.

For newly built sports halls reverberation time must not exceed 1.5 seconds (or 2.0 seconds if 280-530 m2).

For refurbished sports halls, reverberation time must not exceed 2.0 seconds, regardless of size.

Reflection and Sound Absorption

Once emitted from a source, sound waves in hall travel through the air until they reach a boundary surface or other obstacle. When a sound wave reaches a surface it will be partly reflected off the surface back into the hall and continue travelling in a new direction, and it will be partly absorbed by the surface with the absorbed energy being dissipated as heat. Sports facilities are particularly problematic when it comes to echo and reverberation due to the hard wall, floor and ceiling surfaces which are required to withstand years of use from sporting activities.

With the soft, absorptive core sitting flush against the walls of sports halls and the panels having a naked backing, they are fully impact resistant and ideal for sports halls and gymnasiums with high impact activities. The benefit of this solution is that you are able to choose almost any fabric you want to wrap the core with – giving you more design flexibility.

Acoustic solutions for sports halls by using Acoustic panels Acoustima® acoustic panel by Seatup Turkey®  are sound absorbing panels that are hung on a wall or ceiling to control and reduce noise, eliminate slap echo in a room. The objective is to enhance the properties of sound by improving sound quality and soundproofing which concludes any means of reducing the sound pressure with respect to a specified sound source and receptor.

There is also a health and safety benefit with the Acoustima® acoustic panel by Seatup Turkey® -Panels as well, providing prevention of injuries from impact against walls during sport.

How to calculate acoustic value in a building

In addition to providing insulation and acting as a substrate for roofing, in many situations roof insulations also need to provide noise reducing characteristics. Building constructions near airports or other high noise areas require noise reduction principles to be employed. Today, the noise reduction properties of roof insulation must be known to properly design structures in high noise areas. Designing constructions to control noise requires, at a minimum, a basic understanding of terms and methods used to develop design values for various constructions. Sound travels through a building component because it sets up vibrations in that component. Almost all building materials are sufficiently elastic to transmit sound. Therefore, almost all building materials can be set into motion by sound waves impinging upon them. Once construction is set into vibration, it will transmit sound from the source through the construction and the sound will be heard on the opposite side of the construction. The result is sound transmission through construction. Sound travels through a building component because it sets up vibrations in that component. Almost all building materials are sufficiently elastic to transmit sound. Therefore, almost all building materials can be set into motion by sound waves impinging upon them. Once construction is set into vibration, it will transmit sound from the source through the construction and the sound will be heard on the opposite side of the construction. The result is sound transmission through construction. The ability of a construction to transmit sound is dependent upon its mass. The higher it’s mass, the more it is resistant to vibration caused by sound. If the mass were extremely small, even faint sound pressure could move it and thus transmit sound.

In addition to mass, numerous other factors must be considered in proper sound control design. Such factors include background noise level, and transmission through floors, walls and penetrations through the construction (which also includes insulation joints). An acoustical engineer should be consulted when dealing with acoustical design.

Acoustical terms that are important to know before calculating acoustic values:

• Sound Pressure Level:

When it comes down to it, your ears are pretty amazing. They allow you to hear sounds as quiet as a whisper and as loud as a jet engine. How exactly do sound waves get transmitted to your ears so that you can hear?

It starts with a vibration in the air. A whisper only vibrates the air a little bit, while a jet engine vibrates it A LOT. This vibration creates a pressure wave that passes through the air, spreading out in all directions as it goes. Sound pressure is the pressure measured within the wave relative to the surrounding air pressure. Loud sounds produce sound waves with relatively large sound pressures, while quiet sounds produce sound waves with relatively small sound pressures.

Sound pressure, like other kinds of pressure, is commonly measured in units of Pascals (Pa). The quietest sound that most people can hear has a sound pressure of 2 x 10-5 Pa, so this pressure is called the threshold of human hearing.

• An audio frequency or audible frequency:

 is a periodic vibration whose frequency is in the band audible to the average human. The SI unit of audio frequency is the hertz (Hz). It is the property of sound that most determines pitch. The generally accepted standard range of audible frequencies for humans is 20 to 20,000 Hz, although the range of frequencies individuals hear is greatly influenced by environmental factors. In air at atmospheric pressure, these represent sound waves with wavelengths of 17 meters (56 ft) to 1.7 centimetres (0.67 in). Frequencies below 20 Hz are generally felt rather than heard, assuming the amplitude of the vibration is great enough. High frequencies are the first to be affected by hearing loss due to age or prolonged exposure to very loud noises.

• Reverberation time:

is the time required for the sound to “fade away” or decay in a closed space. Sound in a room will repeatedly bounce off surfaces such as the floor, walls, ceiling, windows or tables. Reverberation is one of the most significant acoustic properties of a room. Knowing the reverberation time is essential in characterizing rooms, be they performance spaces, ordinary rooms or open office spaces.

The laboratory method to measure acoustical values to use special instruments.

Also, there are some programs ”acoustics calculator” which provide you with a quick overview of the acoustics in a room. Just type in your room data – measurements and material – and the acoustics calculator generates a precise overview of reverberation time, absorption area as well as other relevant information about acoustics. You can have the report sent to your e-mail or you can print it – either on paper or as a PDF. First select the shape of the room, and second type in length, width, and height. The total area of ceiling, floor, walls, doors and windows is automatically transferred to the further calculation. The total area for doors and windows will automatically be subtracted from the total wall area. Then you can get information about the sound level and its distribution in the building. On the other hand, you can know the exact amount of noise reduction the building needs so that desired special acoustic panels.

Different collection of acoustic panels for celling, walls, flour, and furniture with changing the materials (foam, fabric, metal, wooden, and plastic), color, and style Acoustima® acoustic panel by Seatup Turkey® products are recommended too.

Innovative acoustic solutions

Innovative acoustic solutions

Quality of sound goes down under different conditions in a medium. Due to noise, reflectance, diffusion, and so many kinds of sound characteristics. That needs Innovative acoustic solutions to help enhance sound performance. Which allow us mostly a low cost and comparable differences in speech recognition performance without the use of an amplification system.

1) Acoustic rooms:

Complaining about noise in the workplace can seem trivial to some, but excessive or continual sounds can affect the physical and mental health of employees such as (increased risk of accidents, stress, tinnitus, noise-induced hearing loss, and disturbance of speech communication)

Whether the noise is coming from office machines, chattering co-workers or construction, the effects can lead to an increase in disturbed emotions and a reduction in productivity.

In huge places like factories and offices in companies, the ability to control noise reaching the worker’s ears is inaccurate because the unwanted sounds come from multiple sources and the ordinary acoustic absorbing panels effect become low.

To ensure that employees are able to function properly, acoustic engineers improve a very creative solution which is acoustic rooms.

Acoustic rooms made from special materials which have a high value of sound absorption coefficient.

2) Multipurpose hall:

Buildings which need a specific sound performance utilization like opera hall, theatre, cinema, concert, and speech each one needs its own design for structure and added acoustic panels because they differ in their behaviour to sound like reverberation time, clarity, warmness, and other acoustic parameters.

For profit, utility, efficiency, and of course economy destinations. Multi-purpose hall is designed to reach the perfect sound performance for many implementations. It changes its shape to fit sound conditions that are used for.

In addition to this acoustic panels can appear/disappear or change its angle to reflect more/fewer acoustic waves due to their necessity.

3) Ceiling:

The builders are constantly looking for ways of reducing or eliminating impact noises and airborne noises in their structure. A ceiling acoustic anchoring system is the unique solution where insulators and the ceiling furrings allow the decoupling of the ceiling structure with the gypsum. The mechanical system being equipped with a rubber insert, it absorbs the impact noises and the vibration on the floor above and avoids the vibration noises in the ceiling.

The distinguish come from the benefits that it includes:

Fast and easy to install.

Improved acoustic performance exceeding the highest quality requirements.

No special tools needed.

Compatible with all decking types.
