Periodic high quality calibration of audiology equipment is essential to ensure accurate testing results for patients. In audiometry, calibration ensures that the hearing level shown by the audiometer complies with the British Standard specifying the reference for hearing thresholds.Click to see full answer. Similarly, you may ask, how often should an audiometer be calibrated? three months Likewise, what are the uses of audiometer? An audiometer is a machine used for evaluating hearing acuity. They usually consist of an embedded hardware unit connected to a pair of headphones and a test subject feedback button, sometimes controlled by a standard PC. Such systems can also be used with bone vibrators, to test conductive hearing mechanisms. In this way, what is biological calibration? A biological calibration is a subjective test that starts with a physical examination of the audiometer and all accessories. It is meant to look for any signs of damage to any piece of equipment or accessory – including transducers, ear cushions, plugs, and cords.How do you clean audiometer headphones?Clean headphones before each re-use with a cleaning agent or alcohol-free wipes. Do not use alcohol because it may dry out the rubber cushions on headphones. When the headphone cushions need cleaning, remove them from the headset, clean and dry thoroughly before replacing.
