Absolute threshold of hearing - Wikipedia
The absolute threshold of hearing (ATH), also known as the absolute hearing threshold or auditory threshold, is the minimum sound level of a pure tone that an average human ear with normal hearing can hear with no other sound present.
Absolute Threshold: Definition, Examples, and Uses in Psychology
2023年9月7日 · For hearing, the absolute threshold refers to the smallest level of a tone that can be detected by normal hearing when there are no other interfering sounds present. Whether you can detect a the ticking of a clock in a quiet room would be an example.
Hearing range - Wikipedia
A basic measure of hearing is afforded by an audiogram, a graph of the absolute threshold of hearing (minimum discernible sound level) at various frequencies throughout an organism's nominal hearing range.
Sensorineural hearing impairment often leads to raised absolute thresholds, but the same uncomfortable loudness level. This steeper growth of loudness is known as “loudness recruitment”. Possible physiological basis in the basilar-membrane nonlinearity, and the cochlear amplifier (Moore and Oxenham, 1998; Psych. Rev. 105:108-124):
Absolute threshold - Wikipedia
The absolute threshold of hearing is the minimum sound level of a pure tone that an average ear with normal hearing can hear with no other sound present. The absolute threshold relates to the sound that can just be heard by the organism.
Absolute Threshold: Definition and 10 Examples (2024)
2024年6月2日 · Hearing Threshold: When getting a hearing test, a person’s absolute threshold is the quietest sound they can hear. Depending on their hearing capabilities, it can range from 20-30 decibels. Hearing thresholds in humans also tend to differ based on …
Absolute Threshold of Hearing - Stanford University
The simplest property to exploit is the ATH (Absolute Threshold of Hearing). We simply cannot hear sounds which are too weak. The ATH varies a lot with the frequency of the test sound, which can be seen in Fig. 2. The curve is approximated from experiments on a number of subjects (see [1]). Figure 2: The absolute threshold of hearing.
