概括
外部观察员,包括听力学家,无法检测耳植入物 (CI) 用户重复句子的倾听力. 心理词语修复虽然很费力,但没有留下可靠的语音签名,冒着不被注意到的听力挑战的风险.
科学领域:
- 听觉感知是一种听觉感知.
- 语音处理 语音处理
- 人与计算机的互动.
背景情况:
- 倾听可能需要付出努力,特别是当个人必须用上下文线索在精神上修复错误的词语时.
- 这种认知努力,虽然有记录,但可能无法通过声音变化通过外部检测到.
研究的目的:
- 调查外部观察者是否可以检测耳植入物 (CI) 的人在重复句子时的倾听力度.
- 为了确定与心理词修复相关的声音特征是否能被听众感知,包括受过训练的听力学家.
主要方法:
- 使用了成年人与CI重复完整的句子的音频录音,与需要上下文推断的掩饰词句子相比.
- 171名参与者,包括28名听力学家,在视觉模拟尺度上对刺激进行了评分,以辨别有力听力与无力听力.
- 参与者还报告了他们从声音线索中检测听者的努力或困惑的经历.
主要成果:
- 法官无法在CI用户中可靠地区分有力和无力倾听条件.
- 有一种偏见,认为听众在没有修复的情况下正确处理句子.
- 假设的努力声学相关物 (例如,语音音调,反应时间) 与听众评分没有相关性,听力学家的专业知识没有提供任何优势.
结论:
- 心理词修复,尽管付出了努力,但并不能产生可靠的可感知的语音签名.
- CI使用者的倾听努力可能会被对话伙伴和临床医生所忽视,这可能导致低估患者的困难.
- 该研究强调了倾听努力的内部体验与其外部可检测性之间的差距.

01:28Physical Assessment of the Respiratory Tract IV: Auscultation
227
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.

00:53Sound Intensity Level
4.1K
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...

01:31Respiratory System Abnormal Finding II: Palpation and Auscultation
206
In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

A communication barrier is any distortion or interruption during a conversation, resulting in miscommunication of the message. A good communicator should know these barriers and continuously check for the listener's understanding by obtaining feedback.
Communication barriers include the following:
Physiological barriers: They are limitations caused by a person's health condition or disability, such as hearing loss, poor eyesight, illness, or unconsciousness. An example to overcome this...

Communication is a lifelong learning process. Through therapeutic communication, nurses can collect relevant assessment data, provide education and counseling, and interact during nursing interventions. Sending and receiving messages occur through verbal and nonverbal communication techniques and can happen separately or simultaneously.
Verbal communication depends on language or a prescribed way of using words so that people can share information effectively. The critical aspects of verbal...

The human ear cannot distinguish between two sources of sound if they happen to reach within a specific time interval, typically 0.1 seconds apart. More than this, and they are perceived as separate sources.
Imagine the sound is reflected back to the ears. Assuming that the source is very close to the human, the difference between hearing the two sounds—the emitted sound and the reflected sound—may be more than the minimum time for perceiving distinct sounds. If this is the case,...
