Speech intelligibility in different types of audiograms and speech audiometry by using the simulated hearing loss on the speech material with normal hearing people

Presbycusis and noise-induced hearing loss result in characteristic audiogram curves with increasing levels of at higher frequencies. Another specific form curve is the cookie bite, which often inherited sometimes illness or injury. The influence on speech intelligibility was examined along a list words selected according to frequency range phonemes present. Dependence dominant loss, lower, middle frequencies over whole shown. method audiometry simulated material normal people presented.
