Q. Why do I need my Equipment Calibrated? A. To assure the equipment is accurate to test your patient at a standard it was manufactured for.
Q. Why should I purchase equipment for my occupational health program from Audiometrics rather than my medical supply rep? A. Account representatives from Audiometrics are certified in Audiometry, Spirometry, and Breath Alcohol testing. Complete familiarity with the OSHA regulations, experience in administering tests and the most comprehensive product line in the industry enable us to recommend the right instrument for your specific needs.
Q. What is the difference between OSHA annual and exhaustive calibrations? A.OSHA annual is the output level of the test frequencies at 70 dBHL and attenuator linearity checked from 70dBHL to 10dBHL. OSHA exhaustive is a full ANSI calibration.
Q. Should I purchase a manual or microprocessor audiometer for my Hearing Conservation Program? A. Microprocessor technology has all but taken over the occupational market. The instruments are accurate, fast and effective. A number of audiometers now have the capability to store more than a thousand tests in the memory, compare current tests to baselines, calculate threshold shifts and correct for aging. Whoever reviews the hearing tests and currently is performing these calculations will truly appreciate this feature. The newest innovation in microprocessor audiometers is "Multi Media". A microprocessor audiometer used in conjunction with an audiometric software system can actually give the initial test instructions and coach the patient verbally in case of an error.
Q. Does OSHA require that audiometric testing be done in a sound booth? A. Audiometric testing must be done in an environment that meets or exceeds OSHA's standards for ambient noise. While it is possible to meet those standards in a "quiet room", it is difficult to maintain them with the typical noise generated in a normal office setting. An audiometric enclosure not only ensures compliance with OSHA but it also enables your staff to be more productive. A sound booth used with a microprocessor audiometer will allow your audiometric technician to do other things while the employee is being tested. A test given in a quiet room requires that the technician be in the room and remain quiet during the test.
Q. What is the advantage of using insert phones? A. Reduces the need for masking noise, Increased test/retest reliability, reduces background noise, and will open collapsed canals.
Q. Why is my Audiometer calibrated to ANSI S3.6-1989 or ANSI S3.6-1969 and not the current standard of ANSI S3.6-1996? A. Because your audiometer might be an older machine and needs to only pass an older standard.
Q. Do I need a wheelchair ramp for my sound booth? A. Yes. If the booth in not level with the ground then the ADA requires it. Check the ADA Handbook for Specifications.
Q. What other equipment does Audiometrics provide? A. In addition to audiometers, middle ear analyzers, ABR, ENG, OAE systems , sound booths, spirometers, and software, we sell a variety of ECG instruments, vision testers, breath alcohol testers, otoscopes and ophthalmoscopes, blood pressure instruments, noise measurement equipment and "AED"s (Automated External Defibrillators).
Q. Why use High Frequency Tympanometry? A. For some years it has been recognised that conventional low-frequency probe tone tympanometry is inappropriate for infants below about 7 months of age, because of the poor sensitivity (ie, high false negatives) of conventional tympanometry to middle ear disease in young infants. The main limitation of low-frequency probe tone tympanometry appears to be the presence of Type A tympanograms based on the Jerger/Liden classification (Jerger, 1970; Liden, 1969) despite the presence of middle ear effusion diagnosed otoscopically or surgically. More recently Keefe and Levi (1996) noted that some infants with flat 226 Hz tympanograms have middle ear energy reflectance in the normal range at higher frequencies, which suggests also that false positives as well as false negatives occur when using low-frequency probe tone tympanometry in infants.
