32. Dangerous earphone
The base is demand in the earphones. Now, it is designed in such a way that you cannot listen outside volume. We can know that which earphone is dangerous.
33. How much risky
It blocks the air in the ear, so that the sound give more pressure on ear drum. Scientists believe it is very dangerous. You may have ear problem if you use it for long time.
34. Ear birds
It does not have rubber plug. It fits outside the ear. It has low sound quality compared to in ear headphones. Most of the mobile companies created this. But due to high demand they do not produce it more.
35. Over the ear
It has big ear piece. It has kutions like bowl which cover the whole ear. It is designed for those who work for long hours on sound system. It has very good sound quality compared to ear birds.
36. Understanding the Risks Involved
While music plays a great role in our daily lives, listening to loud music can put undue pressure on your ears and damage your hearing. In fact, about 90% of people experience ringing in their ears after listening to loud music or after using their headphones for long periods of time. While this sensation usually lasts for 24 hours at the most, constant exposure to loud music can increase your risk of tinnitus a physical condition characterized by ringing in the ears even when no such noise is present and or premature hearing loss.
37. Minimizing the Risks
Considering the many benefits of listening to music, a lot of people would naturally be interested to know if there is a way to enjoy these benefits without making themselves susceptible to the abovementioned risks. Thankfully, there are several ways to do it.
38. Loudspeakers fixed to your ears
Headphones which are often called cans by DJs and people who work in radio broadcasting work in exactly the same way as speakers, so you might want to consult our article on loudspeakers if youre not sure how they use magnetism to turn electrical energy into sound.The biggest difference between loudspeakers and headphones is, of course, size. A loudspeaker needs to set all the air moving in a room so you can hear the sound its making, but the speaker in a headphone only has to move the volume of air inside your ear canal. Thats why it can be so much smaller and more discreet.
39. Sensitivity
The sensitivity factor of a headphone amp determines how loud it will play when a certain wattage of power is inputted to it. Also known as efficiency, this value will be stated at the top of the package as a certain decibel level that is achieved with one milliwatt of power. Most efficient headphone amps will provide more than 100dB for every one mV of power.
40. Impedance
Another aspect that users should consider before buying headphone amp is the relationship between headphone impedance and the output impedance of the amp. As a general, the output impedance of the amp should be much lower than that of the impedance of the headphones to get clear and tight sound. It is a good idea to have an output impedance that is at least ten times less than that of headphone impedance.
