Each listener has a stable, individual weighting of frequencies when hearing speech in noise

Evidence

Perturbation analysis has become a popular approach in psychoacoustic research to measure how listeners hear out a target sound in background noise (cf. Berg 1990 ; Lutfi 1995 ; Richards 2002 ). Studies using this paradigm show listeners to have highly replicable, individualistic patterns of decision weights on frequencies affecting their ability to hear out specific targets in noise—what has been referred to as individual listening styles (Doherty and Lutfi 1996 ; Lutfi and Liu 2007 ; Jesteadt et al. 2014 ; Alexander and Lutfi 2004 ). Unfortunately this paradigm is extremely time-consuming, rendering it ineffective for clinical use. Finding a quick and an objective way to measure effective listening in noisy environments would provide a dramatic improvement in clinical assessments, potentially resulting in better diagnosis and treatment. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5760

Categorization

• DEFINE: Introduces ‘individual listening styles’ and ‘perturbation analysis’ as technical concepts for how listeners weight frequencies in noise.
• XREF: The idea of stable individual perceptual styles and the gap between lab measures and clinical tools echoes the reader’s broader theme of how diagnostic instruments flatten individual variation.
