What is considered an output device?
An output device is any piece of computer hardware equipment which converts information into human readable form. It can be text, graphics, tactile, audio, and video. Some of the output devices are Visual Display Units (VDU) i.e. a Monitor, Printer graphic Output devices, Plotters, Speakers etc.
Is headphone analogue output?
Though headphones are regularly connected to digital audio sources, they are innately analog devices. Headphone transducers convert continuously variable (analog) audio signals (electrical energy) into sound waves (mechanical wave energy) and often require a digital-to-analog converter to function.
Are earphones electronic?
They are electroacoustic transducers, which convert an electrical signal to a corresponding sound. Headphones let a single user listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air for anyone nearby to hear.

Are in ear headphones bad for your ears?
Believe it or not, earbuds can damage your hearing in the same way that things like chainsaws and motorcycles can. That may seem weird because earbuds are so small. But the damage is all in the volume. Turning the volume up and listening for long periods of time can put you in real danger of permanent hearing loss.
How long should you use headphones?
“As a rule of thumb, you should only use MP3 devices at levels up to 60% of maximum volume for a total of 60 minutes a day,” says Dr. Foy. “The louder the volume, the shorter your duration should be. At maximum volume, you should listen for only about five minutes a day.”
What volume is safe for headphones?
Experts recommend keeping sound levels at somewhere between 60 and 85 decibels to minimize the damage your ears are exposed to. If you are listening to music at around 100 decibels, restrict your usage to within 15 mins.
Will high volume damage headphones?
False. A headphone or earphone can put out dangerous sound pressure levels (SPLs) before hitting its breakdown volume. That’s the point where the product stops increasing in volume and becomes more distorted. Loud sounds (high SPLs) won’t necessarily damage the product, but excessively high electrical signals can.
Does using headphones cause hearing loss?
Loud music through headphones can damage the inner ear and cause hearing loss. On an Apple iPhone, the maximum volume while wearing headphones is equal to 102 decibels. This means that hearing damage can occur after listening to just a few songs at this range. Even at lower ranges, it’s easy to be within unsafe levels.
