Disease relevance of Loudness Perception

• These findings may result in abnormal loudness perception in sensorineural hearing loss as produced by loudness recruitment and pathological adaptation [1].
• In this investigation, loudness perception was studied in three groups of listeners: normal listeners, listeners with asymmetrical sensorineural hearing loss, and individuals with bilaterally symmetrical hearing impairment due to presbycusis [2].

High impact information on Loudness Perception

• Furthermore, oxazepam had no substantial and systematic influence either on auditory selective attention or on loudness perception [3].
• It is concluded that key properties of sensorineural hearing loss (altered loudness perception, reduced dynamic range, normal temporal properties but prolonged forward-masking effects) can effectively be modeled by incorporating a fast-acting expansion within the current processing model prior to the nonlinear adaptation stage [4].
• The Contour Test appears to offer a viable approach to clinical measurement of loudness perception: It has good patient acceptance and combines fairly rapid administration with acceptable reliability [5].
• A factor analysis identified seven components (speech understanding in demanding situations, speech/language abilities, general behavioural issues, reactions to questions and demands, discrimination of speech sounds, musical cues, loudness perception) underlying the contrasts between the two study populations [6].

Analytical, diagnostic and therapeutic context of Loudness Perception

• The Independent Hearing Aid Fitting Forum uses the visual input/output locator algorithm and the Contour Test of Loudness Perception to achieve the goal of restoring normal loudness perception with amplification [7].
