For the record label named "Audiogram", see Audiogram (label) An audiogram is a Graphical representation of how well a certain person can perceive different Sound Frequencies . An audiogram is a normalised conversion of hearing thresholds from dBSPL to dBHL, where dB is Decibel , SPL is Sound Pressure level and HL is hearing level. Audiograms are set out with frequency in Hz on the horizontal axis, most commonly on a Logarithm ic scale, and a Linear dBHL scale on the vertical axis. Normal hearing is classified as being between -10dBHL and 15dBHL, although 0dB from 250Hz to 8kHz is deemed to be 'average' normal hearing. SEE ALSO |
