概括
音乐家在噪音中改变了音调信息时,不会在语音感知上表现出优势. 然而,与音调和口音处理相关的音乐技能有利于在噪音中听到语音的感知,不管有没有正式的培训.
科学领域:
- 听觉神经科学 听觉神经科学
- 语音感知 语音感知
- 精神声学是一种精神声学.
背景情况:
- 基本频率 (f0) 轮变化对于语音感知至关重要,特别是在杂的环境中.
- 虽然音乐家经常表现出增强的听觉技能,但他们的优势在语音噪音 (SIN) 感知与退化f0信息仍然不清楚.
研究的目的:
- 研究降低f0轮 (词汇音和语调) 对音乐家在SIN感知中的优势的影响.
- 为了确定音乐训练是否会在音高信息被扭曲时带来好处.
主要方法:
- 测试了30名音乐家和30名非音乐家 (中国普通话的母语) 的SIN可理解性.
- 使用自然,平面音调,平面音调和平面音调的所有f0轮的句子,在不同的信号噪声比率 (0, -5, -9dB) 中.
- 评估与SIN福利相关的音高差异值和音乐技能.
主要成果:
- 对所有参与者来说,语音可理解性得到改善,信号与噪声比率更高.
- 对于任何类型的平面 f0 轮的 SIN,没有发现音乐家的优势.
- 音乐家有更好的音调歧视,与完整的语音感知相关的好处.
结论:
- 没有证据支持音乐家对SIN感知具有扭曲的信息的优势.
- 感知性音乐技能 (音调,口音) 独立于正式的音乐培训,可以增强SIN感知.
- 音乐培训对SIN的好处可能不取决于处理f0音调轮,特别是对普通话说者来说.

Perceiving Loudness, Pitch, and Location
239
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...

Perception 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...

Auditory Perception
364
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...

Beats

The study of music provides many examples of the superposition of waves and the constructive and destructive interference that occurs. Very few examples of music being performed consist of a single source playing a single frequency for an extended period of time. A single frequency of sound for an extended period might be monotonous to the point of irritation, similar to the unwanted drone of an aircraft engine or a loud fan. Music is pleasant and exciting due to mixing the changing frequencies...

Difference from Background: Limit of Detection
6.4K
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.

Sound Intensity Level
4.2K
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...
