Webthreshold for hearing at various frequencies. Most speech sounds have frequencies (pitch) that have a wide range: 500-2,000 Hz. The "speech reception threshold" is best defined as the decibel level at which one can understand speech. All of the following identify the location of hearing loss EXCEPT adventitious. WebAbstract Several investigations were perfomed with normal hearing subjects to determine the effects of presentation level and signal-to-babble ratio on the speech perception in noise (SPIN) test. The SPIN test contains sentences that simulate a range of contextual situations encountered in everyday speech communication.
