HOW DANGEROUS YOUR HEADPHONES

 USE OF HEADPHONES - The number of headphones/headsets sold worldwide has increased from 236 million in 2013 to an estimate of 360 million in 2019. The number shows the importance of the device. 

Today, life without a mobile phone can not be imagined. Similarly, the use of mobile phones without headphones is tough to imagine. It is a very important device. People usually going on buses, trains, and planes to carry headphones to listen to music. Also, people use it for the morning walk, the evening walk, runnings, and exercise. In the market, you can get earphones or headphones of the different companies from a very high price at a very low price. Many local companies are making headphones and selling at a very cheap price. Generally, people see the low price and buy headphones. 

USE CAREFULLY - The human hearing range is 20Hz to 20kHz. I tried to find the frequency range of leading company headphones from its websites.

1. APPLE - 5Hz and 21kHz
2. SONY - 12 Hz–22kHz
3. JBL- 20 Hz - 20 kHz
4. PHILIPS - 12 - 23 kHz
5. SAMSUNG - 20 to 20kHz

More you can find on different websites. Now the second important parameter for which you should be careful is the decibel(dB). I tried to find decibels ranges.

180 dB: Rocket at take-off

 140 dB: Jet engine at take-off

 120 dB: Rockband

 110 dB: Thunder

 90 dB: City traffic

 80 dB: Loud radio

 60 dB: Ordinary conversation

 30 dB: Whisper

 0 dB: Softest sound a person can hear

All sounds above 90 dB are damaging the inner ear and even doing irreversible damage above 120 dB.

YOU KNOW & YOU DO NOT KNOW - You know a very well loud voice means high decibels is harmful to your ear. But research publishes in royal society, Sounds that the human ear is unable to detect can affect the inner ear and possibly make it temporarily more prone to damage. This is the conclusion of a study from the Ludwig Maximilian University in Munich, Germany. The study shows that being exposed to inaudible sounds for only 90 seconds can affect the inner ear. It damages the inner part cochlea of the inner ear.

In the cochlea, sound waves are transformed into electrical impulses that are sent on to the brain. The brain then translates the impulses into sounds that we know and understand.

There is a solution to use headphones safely. Please download a sound meter app on your phone and use it whenever to buy ou use headphones to check decibels. Set volume of headphones at 60% of total capacity.
