Answer is Right!
Answer is Wrong!
The correct answer is: B. 80 decibles
Sound is measured in decibels (dB). The higher the decibel level, the louder the sound. Sounds above 80 decibels can cause hearing damage if you are exposed to them for a long period of time.
Here is a brief explanation of each option:
- A. 70 decibles. This is the level of sound at which a normal conversation takes place. It is not loud enough to cause hearing damage.
- B. 80 decibles. This is the level of sound at which a vacuum cleaner operates. It is loud enough to cause hearing damage if you are exposed to it for a long period of time.
- C. 100 decibles. This is the level of sound at a rock concert. It is very loud and can cause hearing damage if you are exposed to it for a short period of time.
- D. 120 decibles. This is the level of sound at a jet engine. It is extremely loud and can cause hearing damage if you are exposed to it for even a short period of time.
It is important to protect your hearing from loud noises. If you are exposed to loud noises for a long period of time, you may experience hearing loss. Hearing loss can be permanent and can make it difficult to understand speech, especially in noisy environments.
There are a number of things you can do to protect your hearing from loud noises:
- Wear earplugs or earmuffs when you are exposed to loud noises.
- Avoid listening to loud music through headphones or earbuds.
- Take breaks from loud noises if you are exposed to them for a long period of time.
- Get your hearing checked regularly.
If you are concerned about your hearing, talk to your doctor.
