SAMPLE DECIBEL LEVELS
Exposure to sounds with decibel levels of 85 or higher for a prolonged period of time poses the risk of hearing loss. The higher the decibel level of sound, the less time is needed before hearing loss from noise can occur.
whisper – 30 dB
conversation – 60 dB
vacuum cleaner, hair dryer – 70 dB
dishwasher, washing machine– 75 dB
restaurants – 80-96 dB
city traffic (inside car) – 85 dB
noisy toys – 90 dB
lawnmower – 90 dB
train, garbage truck – 100 dB
CD players, iPods (max) – 110 -115
power saw, symphony orchestra – 110
leaf blower, chainsaw – 115
stereo – 110-125 dB
fire engine siren, thunderclap – 120 dB
rock concerts – 110-140 dB
fireworks -145 dB
People rarely notice that noise is loud enough to be harmful because hearing loss is rarely uncomfortable or painful. Damage from loud sounds to delicate inner ear structures may occur without causing distress. Symptoms of hearing loss may be only a sensation of fullness in the ears, perception of speech as muffled or distant, and ringing in the ears.
Hearing loss from noise can occur gradually. Although these symptoms may fade when noise exposure lessens, some of the fragile “hair” cells may have been destroyed permanently. Lasting hearing loss results from repeated “insults” to the ear from noise.
Exposure occurs in rural and urban settings; in the workplace; during recreational activities (including movies, restaurants, stadiums and gyms); and at home. Loud music can threaten hearing, especially from extended use of headphones with iPods, personal cassette players and compact disc players.
Noisy toys can be hazardous to children. Potentially posing risk are toys with sirens or horns; musical instruments; squeeze toys; whistles; talking dolls; animated stuffed animals; and battery operated toys that produce sounds.
Hearing loss from noise is preventable. Avoidance of noisy situations; lowering the volume on personal music devices; and wearing earplugs, earmuffs, ear protectors, or a combination of methods when exposed to high decibel sounds over time, is advisable.
