For frequency ranges, we can hear from 20 Hz to 20000 Hz (20 kHz). This is due to a limit on the length of our cochlear basalar membrane. If it were longer, we may be able to hear a greater range.
For loudness, using a standard pressure level (SPL) absolute value system, we can hear at soft as 20 dB SPL (just audible whisper) to about 120-140 dB SPL (which will begin to cause hearing loss and irreversible damage).
A noise level that measures 65 decibels is for a normal conversation on the noise scale. On this scale, 0 decibel is the threshold of hearing and 140 decibels is a jet plane at a distance of about 50 meters away.
The ability to regain lost hearing depends on the cause of the hearing loss. Conductive hearing loss, caused by issues in the middle or outer ear, can sometimes be treated with medication or surgery. Sensorineural hearing loss, due to damage to the inner ear or auditory nerve, is generally permanent, but hearing aids or cochlear implants can help improve hearing.
My sense of hearing is known as audition.
Mice have extremely sensitive hearing. They can hear frequencies that are beyond the range of human hearing and use their keen sense of hearing to be alert to potential threats and communicate with other mice.
There are 3 main classifications of sound. These sounds can be classified by volume, by source, and also by intent.
they have different hearing range
Elephants have very good hearing and sense of smell, but poor eye-sight. Their normal hearing range depends on the volume of sound.

109,000 is below normal range for platelet , it should be 250,000 to 400,000 platelet count.
That depends only on the distance where you are hearing the Big Ben and where you are measuring it. Don't come to close.
Yes, some animals can hear frequencies beyond the normal range of human hearing.
I am 50 years old and have no hearing in one ear and normal hearing in the other since birth. I wear no hearing aids and have never experienced any abnormal disabilities. I talk fine and my hearing is fine.
Usually it isn't. When hearing loss becomes bothersome or problematic, then a hearing aid may be used. In children there can be temporary mild hearing loss due to ear infections (especially otitis media). After antibiotic treatment, normal hearing (or, at least, hearing that was normal for that person before the infection) will return.

The bailiffs are responsible for keeping order in the court. The bailiffs followed James out of the courtroom when his cell phone rang during the hearing.
"Unremarkable bilaterally hearing" means that your hearing in both ears is normal and there are no notable issues or abnormalities detected during the hearing test. It indicates that your hearing is functioning within typical or expected ranges.
