absolute hearing threshold
- Objective To investigate the effects of shock wave exposure on hearing threshold and hair cells injury of guinea pigs.
- Eustachian tube function was disturbed in 48.3% cases, tympanogram was abnormal in 42.0% cases, and air hearing threshold was increased in 33.9% cases.
- Pure tone hearing threshold can be conferred by examining the threshold of ASSR and by using the definite numeral values.
- Researchers found that more than 12% of the children had hearing damage known as noise-induced hearing threshold shifts, or NITS.
