In our environment, we will always hear a certain audible voice. If the sound disturbs the daily activities, then that voice is usually called noise. Noise is very annoying since it disturbs out hearing. When there is exposure to loud sound for long periods, you will find that this will cause hearing loss. Moreover, this can cause permanent hearing loss that can not be healed.
The loudness of sound (sound intensity) is measured by units of decibels (db), while the pitch (frequency) is measured with a sound hertz (Hz). For our hearing damage, it is usually determined by factors such as violence, the pitch, and duration of exposure.
Since noise can damage your ears, you have to protect your ears in order to keep your ears in good condition. There are some things that you can do to protect your ears from this disturbing noise. For instance, for you who work in noisy environments, you are required to wear hearing protectors such as earmuffs and earplugs. Especially, for you who work in an exposed area to noise with an average power of more than 90 db for 8 hours a day.
Instead of finding the noise in the workplace, you can find the noise everywhere even in your own house. But, the noise that occurs in your home has small decibel so that it is not too disturbing, for example the sound of ringing phone. Thus, you do not have to wear the hearing protectors for this condition.
Finally, some sounds that you can find in our daily life will be mentioned as follows. The sounds are mentioned with their decibel so that you can identify whether a certain sound is dangerous for your ears or not.
1. Whisper = 30 db
2. Converse ordinary = 60 db
3. Ringing phone = 80 db
4. Lawn mower = 90 db
5. Hair Dryer = 90 db
6. Bulldozers = 105 db
7. Chainsaw = 110 db
8. Ambulance siren = 120 db
9. Jet engines during take-off = 140 db
10. Firing guns = 165 db
