Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Summary
This summary is machine-generated.

The Russian Matrix Sentence test (RuMatrix test) effectively assesses speech recognition in noise for normal-hearing individuals. Aged listeners demonstrated significantly poorer speech recognition compared to younger adults, highlighting age-related auditory processing differences.

Area of Science:

  • Audiology
  • Speech-Language Pathology
  • Psychoacoustics

Background:

  • The Matrix Sentence Test is a validated tool for assessing speech recognition in noise across multiple languages.
  • Evaluating the Russian version (RuMatrix test) is crucial for its application in Russian-speaking populations.

Purpose of the Study:

  • To evaluate the Russian version of the Matrix Sentence Test (RuMatrix test) in normal-hearing individuals of different age groups.
  • To establish the reliability and validity of the RuMatrix test for use in Russian-speaking populations.

Main Methods:

  • The study involved two stages with participants aged 18-74 years with normal hearing.
  • Speech recognition in noise was measured using the RuMatrix test, determining the signal-to-noise ratio (SRN) for 50% speech recognition (SRT50).
  • Training effects and the impact of varying background noise levels (45-80 dB SPL) were assessed.

Main Results:

  • The RuMatrix test demonstrated high test-retest reliability.
  • A significant detrimental effect of high background noise levels (75-80 dB SPL) on speech intelligibility was observed.
  • Aged listeners (62-74 years) had a significantly worse mean SRT50 (-6.9 dB SNR) compared to young listeners (20-40 years) (-8.7 dB SNR).

Conclusions:

  • The RuMatrix test is a reliable and valid tool for assessing speech recognition in noise in Russian-speaking normal-hearing listeners.
  • Age significantly impacts speech recognition in noise, with older adults performing worse.
  • The RuMatrix test's cross-linguistic comparability makes it a valuable tool for international audiological research.
