背景情况:
- 耳声发射 (OAEs) 是由内耳产生的声音.
- 自发的音声排放 (SOAEs) 是被动生成的OAEs.
- SOAEs与整体耳功能之间的关系需要进一步研究.
研究的目的:
- 调查与耳功能相关的自发性耳声排放 (SOAEs) 的状态.
- 检查SOAE存在与暂时唤起的耳声排放 (TEOAEs),扭曲产品耳声排放 (DPOAEs) 和扩展高频 (EHF) 听力值的测量之间的相关性.
主要方法:
- 包括463名参与者 (222名男性,241名女性;年龄在20-59岁) 具有正常听力值 (≤25 dB HL).
- 参与者被分为三个年龄组:20-29岁,30-39岁和40-59岁.
- 评估包括EHF (9-16 kHz) 听力值和TEOAE,DPOAE和SOAE测量.
主要成果:
- 与没有国有企业的参与者相比,对于TEOAE和DPOAE响应,国有企业的参与者表现出明显更大的振幅和信号噪声比率 (SNR).
- 在没有SOAEs的参与者中,年龄与TEOAE/DPOAE幅度/SNR降低和EHF听力值恶化相关.
- 虽然EHF门随着年龄的增长而恶化,无论SOAE的地位如何,TEOAE/DPOAE措施在拥有SOAE的老年参与者中保持稳定.

The Cochlea
45.2K
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.

Auditory Pathway
5.5K
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.

Anatomy of the Ear

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

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.

The Auditory Ossicles
1.7K
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

Hair Cells
40.7K
Hair cells are the sensory receptors of the auditory system—they transduce mechanical sound waves into electrical energy that the nervous system can understand. Hair cells are located in the organ of Corti within the cochlea of the inner ear, between the basilar and tectorial membranes. The actual sensory receptors are called inner hair cells. The outer hair cells serve other functions, such as sound amplification in the cochlea, and are not discussed in detail here.
