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.

Acoustical solutions for hospitals

Noise in hospitals:
Florence Nightingale (1859) said:
“Unnecessary noise, then, is the cruellest absence of care which can be
inflicted either on sick or well “
As you know hospitals must have a controlled sound level and we all maintain on our quietness when we visit a patient. However, there are many noise sources like speakers’ voice or devices, but WHY that is important issue?

According to US National Library of Medicine Critical Care Journal:
The report noted that noise levels in intensive care units ranged from 50 to 75 dBA, with the highest night peak level even reaching 103 dBA (louder than a lawnmower).

The problem of Noise in hospitals can cause calamity effects which strongly
match sick aside from doctors and employees.
Someone who is a doctor says ”We do mistakes because we can’t hear what is said!”
In additional, sleep and restorative periods should be regular for ill people if not then, additional medication required surgical patients when SPL >60dB (sound pressure level) due to Noise in hospitals.
Noise levels in Johns Hopkins Hospital shows Frequency and Neighbourhood Effects on Auditory Perception of Drug Names in Noise (Lambert) that 3.9 million “wrong drug” errors in US retail pharmacies each year.

(e.g., Zyrtec/Zyprexa, Celebrex/Celexa, Toradol/Tapazole), many due to
confusion between similar names confusion.
Acoustima® acoustic panel by Seatup Turkey® provide acoustical solutions for Noise in hospitals involves insulator solutions and acoustic panels which have absorptivity up to 0.9. Some important numbers about Noise in hospitals:
World Health Organization:
– 0.6 sec reverberation time for patient rooms.
– Lmax(A) no more than 40 dB(A).
– Leq of 30 dB(A) in rooms.

ANSI Standard:
– RC(N) values of 25-45 (Room criteria measures have been developed to
evaluate existing background noise levels in rooms).
US EPA:
– Ldn of no more than 45 dB(A).

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® products are recommended too.

ACOUSTICS IN CONCERT HALLS AND MUSIC ROOMS

Whether it is a large concert hall or a small music room in the school, both need an appropriate acoustic solution.

An appropriate acoustic solution that will help to create an atmosphere in the hall for the music,

Such an atmosphere can be only provides by using the correct acoustic panels,

There must be a combination of panels that receive the sound and swallows to sound in order to avoid echo ,

And panels that serve as a sound blockers to prevent the sound from escaping from the room and also to block noises

From outside the hall that may interfere with the music performed in the hall.

We can not tell you that we are experts in design and design acoustics,

For this what you need to do is to consult with A professional acoustic engineer,

But we are certainly the right address for the production of professional acoustic panels,

The best materials for acoustic panels

There is no doubt that the top Acoustic material in the list of the best materials for Acoustic panels is the Rockwool ,

Rockwool provides the highest level of acoustics at a density of about 110 or at his maximum density of 150.

Another possible material as an alternative to Rockwool for those who have allergy to it, can be the Anti flame

injected foam that is the same material which we use for the producing of our Auditorium seating.

Apart from these two materials Rock wool and injected foam, all other materials in the market are problematic

because either they do not provide the maximum acoustic quality or because they allergic and pollutants for human

and the environment.

Therefore we will recommend our panels made of rockwool or panels made of injected foam in molds.

The field of wooden Acoustic panels it is another topic, it is another area in itself and should not be compared to the

Acoustic fabric panels , since this is a completely different school.

Most of the customers who are looking for wooden panels will not hurry to give up the wooden in favor of fabric

Acoustic panels, the wood has something beyond the high acoustics it gives it is also a design choice which is very

different from the choice of Acoustic fabric panels .

To install panels from the fabric does not require much experience, and can be glued to the wall with silicone glue,

however wooden panels require professional installation with pre-prepared wall profile.

You may choose Acoustic wooden paneling or Acoustic fabric paneling made rock wool or made injected foam in molds.

In both cases we will support you to with your choice and will help you and produce for you what you are looking for.
