I'm just typing this but I don't know. A measured value of an individual's THRESHOLD OF HEARING, expressed in DECIBELs, relative to a specified audiometric standard.
Hearing of speech is considered to be impaired when the hearing level is shifted 25 dB or more, averaged over the 500, 1000 and 2000 Hz frequencies (the region most critical in speech perception). The total impairment level is 1.5 times greater than that for speech. This measurement is not concerned with PRESBYCUSIS, which tends to be considered 'normal'.
The suffix meaning "hearing" is -acusis.
Hearing is simply the biological process of your ear converting sound waves into electrical patterns that are sent to your brain. Listening implies some level of comprehension.. meaning that you can understand and respond to what you're hearing.

dB HL stands for decibels Hearing Level and is a unit used to measure the relative loudness perception for an individual with hearing loss. It represents the volume level of sounds that an average person with normal hearing can hear at a given frequency, serving as a reference point for audiologists to determine the extent of a person's hearing loss.
Hypoacusis is the medical term meaning hearing loss.

Plea of Guilt Hearing- meaning that defendants must show cause as to why they are not party or guilty of what the plaintiff is filing against them.
People should wear a hearing protector if the noise or sound level at the workplace exceeds 85 decibels (A-weighted) or dBA. Hearing protectors reduce the noise exposure level and the risk of hearing loss. If hearing protection is required, then a complete hearing conservation program should be implemented.
85 decibels.
90 db
over a prolonged period of time it harms the ear and makes the person hard of hearing.
