Hearing Conservation

What is noise-induced hearing loss?

• Noise-induced hearing loss is a result of excessive sleep

• Noise-induced hearing loss is a type of hearing loss caused by exposure to loud noises over time, damaging the hair cells in the inner ear.

• Noise-induced hearing loss is a genetic condition

• Noise-induced hearing loss is caused by eating spicy foods

Name two types of ear protection devices.

• Earphones

• Ear covers

• Earbuds

• Earplugs, earmuffs

What are the decibel levels considered safe for hearing?

• Exactly 85 dB

• Between 85-90 dB

• Above 100 dB

• Below 85 dB

How does exposure to loud music affect hearing?

• Exposure to loud music can damage the hair cells in the inner ear, leading to hearing loss.

• Listening to loud music only affects vision.

• Loud music has no impact on hearing.

• Exposure to loud music improves hearing abilities.

What are some occupational hazards that can lead to hearing loss?

• Exposure to loud noises, machinery noise, explosions, and prolonged exposure to loud music.

• Exposure to bright lights

• Wearing sunglasses indoors

• Consuming spicy foods

How can noise-induced hearing loss be prevented?

• Use ear protection, keep volume at safe levels, take breaks, avoid prolonged exposure to loud sounds.

• Wear sunglasses

• Listen to loud music constantly

• Ignore warning signs of hearing loss

Explain the purpose of earmuffs as ear protection devices.

• Earmuffs are used to listen to music in a noisy environment.

• Earmuffs are used to improve hearing ability.

• Earmuffs are designed to keep ears warm during winter.

• Earmuffs serve as ear protection devices by reducing exposure to loud noises or extreme temperatures.

What are the effects of prolonged exposure to high decibel levels?

• Enhanced cognitive function, better sleep quality

• Hearing loss, tinnitus, stress, sleep disturbances, and other health issues

• Decreased risk of heart disease, improved immune system

• Improved hearing, reduced stress levels

Why is it important to limit exposure to loud music?

• To prevent hearing damage and potential long-term hearing loss.

• To increase body temperature

• To improve eyesight

• To enhance taste buds

Discuss the role of engineering controls in reducing occupational hearing hazards.

• Engineering controls increase noise exposure in the workplace

• Engineering controls play a crucial role in reducing occupational hearing hazards by modifying the work environment to minimize noise exposure.

• Engineering controls are only effective in reducing visual hazards

• Engineering controls have no impact on occupational hearing hazards
