On a 1978 flight to Europe, Amar Bose, the founder of Bose Corporation, put on a pair of airline-supplied headphones, only to find that the roar of the jet engines prevented him from enjoying the audio.He started making calculations right there on the plane to see if it was possible to use the headphones themselves as a noise-reducing agent. When most people think of waves, they think of water waves, like you'd seen in an ocean or lake. Sound waves have many of the same characteristics as water waves, but they are longitudinal waves, created by a mechanical vibration in a medium that produces a series of compressions and rarefactions in a medium.
Next, we'll look at how headphones take advantage of some of these same principles to help people hear music, books on tape or other recorded material. Luckily, there's a piece of audio equipment designed especially to maximize your listening experience, keeping ambient noise out without sacrificing your music's sound quality.

You can check out How Speakers Work for some information, but we're also going to provide a brief introduction here.
A shallow water wave is an example of a transverse wave, which causes a disturbance in a medium perpendicular to the direction of the advancing wave. Frequency determines the pitch, with higher frequencies producing higher pitch notes and lower frequencies producing lower pitch notes.
We carry the largest selection of Mobile Electronics and In Car Entertainment systems in Malaysia! That piece of equipment is the headphone, and in this article, we're going to look at how headphones, especially noise-canceling headphones, work. The distance between two compressions, then, is the wavelength, while the amount the medium compressed is the amplitude.
The brain is able to interpret these characteristics of sound, but before that can happen, the sound waves must be detected by a sense organ.

This results in an area where all of the air molecules are pressed together and, right beside it, an area where air molecules are spread far apart.
The distance between any two crests (or any two troughs) is the wavelength, while the height of a crest (or the depth of a trough) is the amplitude. As these compressions and rarefactions move from one point to another, they form a longitudinal wave, with the disturbance in the medium moving parallel to the direction of the wave itself.
