3. OPERATING PRINCIPLES

According to audiometry standards ANSI S3.1 and ISO 8253-1, audiometric
tests should be carried out in conditions where environmental noise does not
mask the results of these tests.
To this end, the booth is an acoustically-isolated enclosure where interior
background noise is very low compared to outside noise, allowing audiometric
tests to be performed correctly.
The booth has panels that contain different layers of sound-attenuating ma-
terial. The basic principle that produces the sound attenuation is known as
the law of mass. Other considerations to take into account in order to have
good sound attenuation are based on the suitable combination of materials, as
well as their dimensions, all of which avoids undesirable effects such, as the
matching effect. (For further information, consult soundproofing and Acoustic
conventions).

4. TREATMENT, PREVENTATIVE AND CORRECTIVE MAINTENANCE

Like any other piece of equipment, the S40 soundproof booth requires treat-
ment and maintenance, to guarantee the reliability and accuracy of the func-
tions for which it has been designed. This implies carrying out a series of
routine tasks.

4.1. TREATMENT

The treatment is the action of maintaining the equipment in good working
order; the person performing this task does not require any specific technical
training, except knowledge of how to handle the equipment and its functions.
Normally, this will be performed by the user of the equipment. The operations
to be performed are:
The outside of the booth should be cleaned with soap and water, and then
dried. On the inside of the booth, the foam walls and carpeted floor may be
cleaned with a conventional vacuum cleaner: the plastic parts and the window
may be cleaned with soap and water.
Do not use abrasive or solvent substances that may damage the finish of the
booth.
