What is the threshold of tactile feeling in HL?

The threshold of tactile feeling is an important consideration in the field of audiology when discussing degrees of hearing loss (HL). The correct range for the threshold of tactile feeling is typically around 100-110 dB HL. At sound levels within this range, individuals may begin to feel vibrations as opposed to just hearing sounds. This level is significant because it indicates that the auditory system is no longer just processing auditory information but also responding to tactile stimuli.

The ranges provided in the other options do not accurately reflect the standard thresholds used within audiological assessments. Lower thresholds, such as those listed in the first two options (80-90 dB and 90-100 dB HL), would correspond to levels of hearing loss that can still be perceived by individuals as sound rather than as tactile sensation. Therefore, their inclusion in the list does not accurately represent the tactile threshold, which is generally accepted to be around 100-110 dB HL. The upper ranges also do not reach the correct threshold required to indicate tactile response.

Understanding these thresholds is crucial for audiologists and hearing dispensers when diagnosing the severity of hearing loss and determining appropriate interventions.
