背景情况:
- 与年龄相关的变化可能会影响听觉处理,包括语音噪音感知 (SINP).
- 了解衰老对SINP的影响对于识别和管理老年人听力挑战至关重要.
研究的目的:
- 研究年龄对语音噪声感知 (SINP) 的影响,使用白噪声中的词感知得分 (WPS in WN).
主要方法:
- 一项涉及76名参与者 (30名老年人,46名年轻人) 的横截面研究,他们的认知和压力水平正常.
- 听力学评估包括近距离测试,纯音声听力测试,语音接收值和WPS在WN中.
- 数据使用曼·惠特尼和图基HSD测试进行分析,参与者被分为年轻正常听力,老年正常听力和有听力损失的老年人.
主要成果:
- 在年龄组和听力状况之间观察到WN中WPS的显著差异,特别是老年参与者的左耳.
- 无论是年轻人还是老年人,在两个耳朵的各种信号对噪声比率 (SNR) 中,WN中的WPS都显示出显著的差异.

01:01Perception of Sound Waves
4.5K
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...

The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...

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.

01:30Cognitive Development During Adulthood
155
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

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...
