Jerger hearing thresholds
WebAbove this level, the reflex threshold is usually elevated in proportion to the degree of loss • The average acoustic reflex threshold to a pure tone is 85 dB and to a BBN signal is closer to 65 dB. Sensorineural hearing loss has a differential effect on the two signals, raising the threshold to BBN signals, but not to pure tone signals Web1. Introduction. Sudden sensory neural hearing loss (SSNHL) is defined as sensory neural hearing loss that appears within 72 h and is manifested by a decrease of at least 30 decibels (dB) in three consecutive frequencies in audiometry ().The annual incidence of SSNHL is 5–27 people per 100,000 (), with a 32–65% chance of spontaneous recovery without …
