Audiology Cabin


Our Audiology Cabin is a product of standard design,fully equipped and furnished to provide noise-secure facilities for routine threshold screening of personnel in normal-'quiet ambient noise level surroundings.The cabin which is suited to many industrial,educational and military applications requires only simple plug in link up to an external power supply and audiometer for immediate operational use. The booth is ideal for use in conjunction with industrial hearing conservation and noise monitoring programs.

Audiology cabin fully equipped with a silenced ventillation system. For audiology cabin with air and bone conduction, Speech and all tests. Audiology cabin comfortable climate in the chamber due to sound attenuated airing system. Large observation window of multilayer safety glass.

The audiometric test can be carried out using automatic or manual audiometers, but the essential test procedure is the same:

  • The subject is asked to remove anything which might upset the test results, e.g. spectacles, earrings, hearing aids and he/she is placed within the audiology cabin while the examiner is seated outside the cabin.
  • Instructions are given about the test procedure and the subject is required to indicate whether he/she can just hear or cannot hear a certain sound (the sound level may be increased from a very low level or reduced from a high level).
  • Headphones are fitted carefully over the ears and the test is then carried out on each ear.
  • First of all, a threshold test is undertaken in which each ear is subjected to sound at a mid-range pitch or frequency of 1 kHz at varying degrees of loudness (in a decibel range) ranging from low to high and high to low. The procedure is repeated several times so that an average threshold can be derived from the test. Thresholds can vary due to slight changes in the procedures adopted in setting up the test, e.g. variation of the position of the earphone on the ear.
  • Following this pre-check, both of the subject’s ears are tested through a range of frequencies (usually 0.5, 1, 2, 3, 4 6 and 8 kHz) and hearing loss recorded for each frequency, again via a series of sound exposures. From the readings obtained, an average result can be computed.
