If a person’s hearing threshold is between 0 dBHL and 20 dBHL, the hearing is within normal limits. Hearing loss is identified as any threshold at any frequency that is over 20 dBHL.

Is 7 Hz dangerous?

Especially dangerous is infrasound at the frequency of 7 Hz, since this sound, generating frequencies, close to characteristic frequencies of the organs of our body, may disturb the heart or brain activity. Machines, natural sources storms, earthquakes, hurricanes, etc. generate infrasound.
