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. The absolute threshold relates to the sound that can just be heard by the organism.
The ear's shape also allows the sound to be heard more accurately. Many breeds often have upright and curved ears, which direct and amplify sounds. As dogs hear higher frequency sounds than humans, they have a different acoustic perception of the world. [24] Sounds that seem loud to humans often emit high-frequency tones that can scare away dogs.
Listener fatigue (also known as listening fatigue or ear fatigue) is a phenomenon that occurs after prolonged exposure to an auditory stimulus. Symptoms include tiredness, discomfort, pain, and loss of sensitivity. Listener fatigue is not a clinically recognized state, but is a term used by many professionals.

Normal human ears can discriminate between two frequencies that differ by as little as 0.2%. [14] 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).
Easy setup. The Avantree Ensemble headphones are a snap to set up. Just plug the transmitter into the proper port on your TV — it will most likely look like a headphone jack, or the same port ...
The hearing aid comes in two rechargeable styles—behind-the-ear with a small receiver attached to a thin wire that sits in your ear canal or behind-the-ear with the receiver resting over the top ...
There can be damage either to the ear, whether the external or middle ear, to the cochlea, or to the brain centers that process the aural information conveyed by the ears. Damage to the middle ear may include fracture and discontinuity of the ossicular chain. [77] [78] Damage to the inner ear (cochlea) may be caused by temporal bone fracture ...
