Normal hearing is in the range of 0 to 20 decibels. Sound Frequency (Pitch) Frequency is measured in hertz (Hz).A person who has hearing within the normal range can hear sounds that have frequencies between 20 and 20,000 Hz.The most important sounds we hear every day are in the 250 to 6,000 Hz range. I am 37, I can hear up to 16 kHz flat as a pancake, then it rolls off fast to 17kHz where I can barely hear anything. Hearing loss range (dB HL) Normal –10 to 15: Slight: 16 to 25: Mild: 26 to 40: Moderate: 41 to 55: Moderately severe: 56 to 70 : Severe: 71 to 90: Profound: 91+ Source: Clark, J. G. (1981). I have tried with a few different speakers and headphones. A normal body temperature for infants aged 0–2 years ranges from 97.9–100.4°F when taken rectally. Hearinglevels of Adults by Age and Sex UnitedStates,19664962 Series 11 11 PROPERNOFlWE -' PUBLICATIONSBRANCH EDITORJALLIBRARY Distributions of hearing levels of adults by age and sex at frequen­ cies of 500, 1000, 2000, 3000, 4000, and 6000 cycles … An audiogram can be obtained using a behavioural hearing test called Audiometry. If you can only hear sounds when they are at 30 dB, you have a mild hearing loss. The hearing range of humans gets worse with age. Asha, 23, 493–500. Normal hearing ranges from 0 to 20 dB in all frequencies.

17 Results are recorded as pass, indi- cating that the patient’s hearing levels are within normal People with normal hearing are able to make out sounds as faint as human breathing, which measures about 10 decibels. From here on, the assumption is that you have a sensorineural hearing loss (that you have nerve damage to the inner ear). People lose the ability to hear sounds of high frequency as they get older. An audiogram is a graph that shows the audible threshold for standardized frequencies as measured by an audiometer.The Y axis represents intensity measured in decibels and the X axis represents frequency measured in hertz. Also, the hearing range for men worsens more quickly than the hearing range for women. Uses and abuses of hearing loss classification. its of normal hearing (25 to 30 dB for adults, and 15 to 20 dB for children). The highest frequency that a normal middle-aged adult can hear is only 12-14 kilohertz. its of normal hearing (25 to 30 dB for adults, and 15 to 20 dB for children). For conductive hearing losses, see your otolaryngologist (your ENT physician). Chiming in with my range results. Dolphin sounds are usually within the hearing range of people. On the other side of the human hearing range, the highest possible frequency heard without discomfort is 20,000Hz. I can still make out up to 20kHz but I need to turn the volume way up. For a person with normal hearing, when it comes to pitch the human hearing range starts low at about 20 Hz.

For a normal person hearing range starts low about 20 Hz. That’s about the same as the lowest pedal on a pipe organ.
