Summary
This summary is machine-generated.Indian classical music training, especially for percussionists, enhances speech-in-noise perception and reduces listening effort in challenging auditory conditions. This musician advantage is most pronounced in difficult listening scenarios.
Area Of Science
- Auditory Neuroscience
- Psychoacoustics
- Music Perception
Background
- Musical training is linked to experience-based plasticity in speech-processing networks.
- The impact of musicianship on listening effort (LE) for speech in degraded environments is understudied.
Purpose Of The Study
- To investigate the influence of Indian classical music training on speech-in-noise (SIN) perception.
- To assess the effect of music training on listening effort (LE) in challenging auditory conditions.
Main Methods
- A quasi-experimental design involved 16 percussionists, 17 non-percussionists, and 26 non-musicians (aged 18-35, normal hearing).
- Musical abilities were assessed using the Mini-Profile of Music Perception Skills (Mini-PROMS).
- Speech-in-noise (SIN) perception and listening effort (LE) were measured using standardized tests and pupillometry at varying signal-to-noise ratios (SNRs).
Main Results
- Percussionists showed superior performance in specific Mini-PROMS subsets (Tuning, Speed) compared to non-percussionists.
- Percussionists demonstrated significantly better SIN perception and reduced LE at -5 dB SNR for words and at 0 dB and -5 dB SNR for sentences compared to both non-percussionists and non-musicians.
Conclusions
- Percussionists exhibit the most significant advantage in decoding speech in noise with diminished listening effort.
- A clear hierarchy of benefit was observed: percussionists > non-percussionists > non-musicians, particularly in demanding listening situations.

The respiratory system, fundamental to life, consists of complex structures responsible for gas exchange. The percussion assessment is critical to understanding this system's health and functionality. This non-invasive assessment technique allows healthcare providers to evaluate the density or aeration of the lungs, thereby identifying potential abnormalities.

The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...
The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same...
