   • In general, there is a tendency to underamplify the extreme ends of the musical scale and to overamplify certain particular frequencies below the middle, such as originate from acoustic resonance. 1933, Keith Henney, The Radio Engineering Handbook, page 286:
   • Physiological thresholds can differ from behavioral thresholds by ±15–20 dB HL. Thus, without verification of behavioral responses with amplification, hearing aids may underamplify or overamplify. 2006, Patricia Spencer, Advances in the Spoken-Language Development of Deaf and Hard-of-Hearing Children, →ISBN:
   • What is interesting to note here is that the 2⁄3 gain can be seen to overamplify over the curved line of the impaired ear more than underamplifies, whereas the 1⁄3 gain curve illustrates the opposite, where it tends to underamplify sound to the ear. 2014, Michael J.
