Key Takeaways: An audiogram shows the softest sounds (volume: soft to loud) you hear at each frequency (low to high pitches). The lower the line on the graph, the worse your hearing is at that ...
For instance, two recognized sources of high-pitched sounds might be electromagnetic fields common in modern wiring and various sound signal transmissions. A common and often misdiagnosed condition that mimics tinnitus is radio frequency (RF) hearing, in which subjects hear objectively audible high-pitched transmission frequencies that sound ...
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. [4] Behavioural hearing tests or physiological tests can be used to find the hearing thresholds of humans and other animals.
Upper line: average hearing thresholds. Lower long line: LDLs of this group. Lower short line: LDLs of a reference group with normal hearing. [40] The basic diagnostic test is similar to a normal audiogram. The difference is that, in addition to the hearing threshold at each test frequency, the lowest uncomfortable sound level is also measured.
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 ...
Tinnitus is described as hearing a sound when an external sound is not present. [13] Noise-induced hearing loss can cause high-pitched tinnitus. [14] An estimated 50 million Americans have some degree of tinnitus in one or both ears; 16 million of them have symptoms serious enough for them to see a doctor or hearing specialist.
