Summary
Even mild hearing loss can alter adult voice patterns, with distinct differences observed between males and females. Voice parameters like fundamental frequency and jitter are affected by hearing impairment.
Area of Science:
- Audiology
- Speech-Language Pathology
- Otolaryngology
Background:
- Hearing impairment can impact various physiological functions.
- Voice production relies on auditory feedback, suggesting a link between hearing and vocal characteristics.
Purpose of the Study:
- To investigate the relationship between hearing levels and voice parameters in adults.
- To compare voice characteristics across different degrees of hearing loss.
Main Methods:
- Utilized the Multi-Dimensional Voice Program (MDVP) and electroglottography for voice analysis.
- Categorized subjects into three groups based on hearing thresholds: normal hearing (<25 dB), mild-to-moderate hearing loss (25-60 dB), and moderate-to-severe hearing loss (60-90 dB).
- Evaluated voice parameters separately for male and female participants.
Main Results:
- In females, significant differences in fundamental frequency (F0), jitter, and soft phonation index (SPI) were noted between normal hearing and mild-to-moderate hearing loss groups.
- Both females and males showed significant alterations in parameters such as maximum phonation time (MPT), jitter, and variable F0 (vF0) with increasing hearing loss.
- Specific voice parameters like shimmer and %shimmer were significantly affected in males with moderate-to-severe hearing loss compared to normal hearing.
Conclusions:
- Mild to moderate hearing loss can significantly affect adult voice patterns.
- Gender-specific differences exist in how hearing loss impacts certain voice parameters.

01:01Perception of Sound Waves
5.9K
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.

00:53Sound Intensity Level

Humans perceive sound by hearing. The human ear helps sound waves reach the brain, which then interprets the waves and creates the perception of hearing. The loudness of the environment in which a person is located determines whether they can distinguish between different sound sources.
The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and...

01:13The Cochlea
52.3K
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.

01:05Difference from Background: Limit of Detection
8.8K
The limit of detection (LOD) is the smallest amount of analyte that can be distinguished from the background noise. The LOD value corresponds to the concentration at which the analyte signal is three times larger than the standard deviation of the blank signal. Below this value, the analyte signal cannot be differentiated from the background noise. It is calculated by dividing the calibration slope by 3 times the standard deviation of the blank signals.

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...

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.
