Hard of Hearing (HoH) Hard of Hearing (HoH) refers to someone who doesn't hear well. This may be because they were born with a hearing loss or they may have lost some or all of their hearing later in life. Many hard of hearing people don't know that they have a hearing loss. Some simply deny it, even though they may know that their hearing is diminished. Some people who are completely deaf may consider themselves hard of hearing. In all, nearly 10% of all people have some level of hearing loss.
A decibel dB(A) is a unit of measurement that indicates how loud a sound is. Humans can hear sounds between 0 and 140 decibels. 0 decibel does not mean that there is no sound, merely that we cannot hear it. 0 decibel is the so-called hearing threshold for the human ear. While we can hear more than 140 decibels, it is too painful for our ears and if you expose yourself to such a loud noise you are at extremely high risk of permanent damage to your hearing. The table blow shows how loud sound is.
