Abstract
ObjectivesAcoustic immittancemetry measurement is made using a probe tone or click stimulus at a frequency of 226 Hz, which is included in the audiological test battery. This study aims to compare tympanometric peak pressure (TPP), static acoustic admittance (Ytm), equivalent external ear canal volume (Vea) and tympanometric width (TW) values measured with probe tone and click stimulus at 226 Hz frequency.DesignMeasurements were made with a probe tone and click stimulus at frequency of 226 Hz in 60 ears of 30 adult individuals with normal hearing between the ages of 18–26. In the measurements TPP, Ytm, Vea and TW values were determined for both ears.ResultsIn two different tympanogram measurement results using 226 Hz click stimulus and 226 Hz probe tone were a statistically significant difference was found between Ytm, Vea and TW values in the left ear (p < 0.05) and a statistically significant difference was found between Ytm and Vea values in the right ear (p < 0.05). There was no significant difference between the right ear TPP and TW values, left ear TPP value (p > 0.05).ConclusıonThe current findings show that the comment of right and left ear tympanogram results should be evaluated according to two different measurement results using 226 Hz click stimulus and 226 Hz probe tone.
