Sound coming from the left arrives first to the left ear and microseconds later to the right ear. Head muffles the sound making the sound louder to the left ear than to the right ear. The head and other parts of the body deflect the sound thus changing the sound's frequency spectrum along its way from the left side to the right side.
The outer ear pathway corresponds to the sound pressure generated in the ear canal cavity due to the vibration of the ear canal wall, which constitutes the source of the occlusion effect. At low frequencies, the outer ear pathway is negligible when the ear canal is open but dominates when it is occluded.
Here's what experts say about the superstition and meaning behind that persistent ringing noise and/or feeling in the ear on your left side—including how it might involve shared energy ...
The central concept behind transaural stereo is that there are two loudspeakers and a single listener (two ears). The left-channel signal should only reach the left ear and the right-channel signal should only reach the right ear, each with appropriate timbral corrections. To effect this, a circuit or computer algorithm is devised.
Older dichotic listening tests that provide normative information for the right and left ears can be used to supplement these two tests for support of the diagnosis ([1]). If performance across two or more dichotic listening tests is normal in the dominant ear and significantly below normal in the non-dominant ear, a diagnosis of amblyaudia can ...
According to Frey, the induced sounds were described as "a buzz, clicking, hiss, or knocking, depending on several transmitter parameters, i.e., pulse width and pulse-repetition rate". By changing transmitter parameters, Frey was able to induce the "perception of severe buffeting of the head, without such apparent vestibular symptoms as ...
In space, no one can hear you scream -- but you may hear a knock.
If one ear has normal thresholds while the other has sensorineural hearing loss (SNHL), diplacusis may be present, as much as 15–20% (for example 200 Hz one ear => 240 Hz in the other). [citation needed] The pitch may be difficult to match because the SNHL ear hears the sound "fuzzy". Bilateral SNHL gives less diplacusis, but pitch ...
