Normal listeners imagining tinnitus report higher loudness than patients with actual tinnitus. This suggests subjective loudness perception differs between feigned and real tinnitus experiences.

Area of Science:

  • Audiology
  • Psychoacoustics
  • Tinnitus Research

Background:

  • Tinnitus, an auditory perception of sound without an external source, affects millions globally.
  • Accurate loudness measurement is crucial for understanding tinnitus and developing treatments.
  • Subjective reporting of tinnitus loudness can be influenced by various factors.

Purpose of the Study:

  • To assess tinnitus loudness perception in healthy individuals feigning tinnitus.
  • To compare loudness judgments between feigning individuals and actual tinnitus patients.
  • To investigate factors influencing loudness matching in both groups.

Main Methods:

  • Healthy participants and tinnitus patients underwent loudness matching tasks.
  • Participants imagined a constant monaural tonal tinnitus.

  • Loudness judgments were recorded with and without external references and across different time intervals and frequencies.

    • Main Results:

    • Normal listeners feigning tinnitus reported significantly higher loudness, especially without external references, after a week, and for low frequencies.
    • Tinnitus patients showed no significant differences in loudness judgments across sessions or frequencies.
    • Variability in loudness matching was similar between feigning normals and tinnitus patients within sessions and over a week.

    Conclusions:

    • Healthy individuals asked to feign tinnitus tend to overestimate loudness compared to tinnitus patients.
    • External references, time intervals, and tone frequency impact feigned tinnitus loudness perception.
    • Findings highlight potential differences in subjective loudness perception between feigned and genuine tinnitus.
