- 神经科学是一个神经科学.
- 生物医学工程 生物医学工程
背景情况:
- 耳死区域 (DRs) 由于损坏的毛细胞或神经元,在噪音中损害了语音感知.
- 像TEN测试这样的行为测试可以检测DRs,但需要患者的合作,限制婴儿和儿童的使用.
- 需要进行电生理学测试,以客观地诊断非合作性个体的DR.
研究的目的:
- 评估和比较三个用于检测声学变化复合体 (ACC) 的电生理学方法.
- 评估ACC检测的效率和速度,使用根平均平方,信号对噪声比 (SNR) 和引导方法.
- 检查ACC特征 (振幅,值) 和刺激参数 (频率,强度) 之间的关系.
主要方法:
- 评估了三种ACC检测方法:N1-P2振幅的平方根平均值,SNR和一种新的引导重新抽样技术.
- 在23名正常听觉的成年人中,使用纯色调 (1kHz,4kHz) 进行了测试,在各种SNR中呈现出值均衡噪声 (TEN).
- 分析了ACC检测效率,给药时间以及刺激频率和强度对ACC值的影响.
主要成果:
- 引导方法在检测ACC方面表现出最高的效率.
- 与英国听力学学会推的SNR方法相比,启动方法的管理速度大约是两倍.

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.

1.4K
Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...

01:28Physical Assessment of the Respiratory Tract IV: Auscultation
3.8K
Auscultation is a crucial component of the physical assessment of the respiratory tract. It offers valuable insights into airflow through the bronchial tree and potential lung obstructions. This process involves careful listening to breath, voice, and adventitious sounds, which can reveal a wealth of information about a patient's respiratory health.
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.

Cardiac auscultation is a clinical skill used to assess heart function and detect abnormalities. It involves listening to heart sounds at specific anatomical locations through a stethoscope.
Normal Heart Sounds
S1 (First Heart Sound)-
S1 is made by the closure of the mitral and tricuspid valves (atrioventricular valves), marking the beginning of systole.
S2 (Second Heart Sound)-
S2 is made by the closure of the aortic and pulmonic valves (semilunar valves), marking the end of the systole.
