1) What is an Audiology Room?
It is technically Acoustically Treated Audiometric Testing Room used for carrying out various audiological tests by audiologist, ENT specialist doctors for hearing aid evaluation. In short, it is used for testing EARS.
2) What is its layout?
Usually there are single, double and three room set up layouts. Three room set up is said to be most professional set up.
3) How it is constructed?
The actual construction have following major aspects.
- Civil construction according to layout.
- Acoustic construction for sound insulation and sound absorption.
- Electrical & instrument wiring for connecting Audiological instruments etc.
- Air conditioning.
4) What is the minimum size required for audiometry?
Usually bigger the size, better is the audiometry. However, audiological booths of 4’ x 4’ carpet area are used for Pure tone audiometry. For paediatric audiometry, bigger size is desired. For audiometric room, minimum size required is between 100 to 150 sqft with proper side lengths. However, exact requirement can be ascertained only after studying the audiological screening tests to be performed.
5) How much time is required for construction?
Usually it takes three weeks for the construction of multiple frequency room. However, Gypsum and fabric based rooms can be completed within ten days also.
6) What are the different types of the Audiology Rooms Setups available with you?
We install various types of rooms according to customer’s requirement, budget, availability of material, ambient conditions, architectural limitations etc. & also according to audiological tests to be performed and number of tests to be conducted simultaneously. Broadly there are two types
- Audiometric testing Rooms
- Audiology booths.
There are also single frequency and multiple frequency rooms, but we manufacture Multiple Frequency Rooms.
7) What material is used in acoustical testing?
The material used is normally conforming to the site conditions. Materials used are mainly of two type:-
A) Acoustically active material – They are mainly responsible for achieving every acoustical parameter. Acoustical designs are made considering these materials. These are categorized in sound absorbing materials and materials offering acoustical aperture. These are normally fibrous materials or open cell structured.
Some of them are :-
– Glasswool & Rockwool of designed density and thickness for high frequency absorption
– Perforated Hard Boards, Gypsum boards for providing acoustical aperture.
– Plywood of different thickness for low frequency bandwidth.
– Compressing material for insulation like rubber seals, hitlon, superlon, etc.
– Sound cleats – metal or wooden for acoustical coupling.
– Acoustical tiles, Acoustic fabric, Acoustical mat, etc.
B) Material to support suitable placement of acoustical material – These materials are mainly responsible for durability of installation. We use best quality material available in the market. These could be best quality ceiling GI or aluminium sections, good quality hardware, formica, adhesive, etc.
8) What is acoustical integrity and why is it important?
Acoustical integrity means capacity to retain acoustical parameters stable for long period of time. If parameters change after some period, then room becomes unfit for audiological screening tests & results become unfaithful. Standard quality of material, design and workmanship ensures acoustical integrity.
9) What are acoustical parameters necessary for audiometric testing rooms and what are their roles?
The major parameters are:-
- Maximum Permissible Ambient Noise Level (MPANL) – This is extremely important parameter and is
specified by ANSI standards for every octave band of frequency. If this is not met, then thresholds won’t
be correct and the tests performed may be unfaithful.
- Transmission Loss – This is a single digit Acoustical parameter which determines noise level inside
the room. We quote this after installation and whenever required by client.
- Noise criteria – This is also single digit acoustical parameter which is designed as desired by client.
This is very important.
- Reverberation time – This is acoustical parameter measured in time. Shortly, it is time taken to diffuse
60dB(A) sound. It is very important parameter as audiological speech related tests can’t be performed
effectively, if reverberation time is incorrect.
- Articulation Index – This is also very important parameter. Audiological speech related tests can’t be
performed effectively without good articulation.
- Magnetic intensity – This should be as low as possible as it interfere with signal causing unwanted noise.
