When we kjøpe solbriller or buy sunglasses, the main intent is to aid our eyes in screening or filtering light as well as shield our eyes from ultraviolet (UV) rays that might add to eye conditions like mascular disintegration and cataracts. Apart from protection from sunlight, sunglasses are also used as an accessory to enhance one’s look and fashion style. Today, many glasses has been developed to be more than just an eyewear that shields light and a fashion accessory.
Since many delight in music, eyewear makers as well as tech companies are working in partnership to create smart glasses wherein they have incorporated a feature for wearers to be able to listen to music, podcast as well as other audial content.
Perceiving Sounds via Bone Conduction
Sounds are heard through our eardrums, which is transmitted or conducted by air, and through our bones, which is conducted or transmitted by our bones. However, most of the sounds that we hear are heard via our eardrums, which changes the sound waves into vibrations and conveys them to the inner ear known as cochlea. But, in certain circumstances, vibrations are directly heard by the cochlea by means of passing the eardrums. Actually, this is one way we hear our own voices. This likewise is how whales are able to hear underwater.
Bone Conduction was discovered by the celebrated composer, Ludwig van Beethoven, who was nearly entirely deaf. Beethoven discovered a means to hear the piano sound via his jawbone by means of affixing a rod onto his piano and clasping it by his teeth. He was able to perceive sounds through his jaws when vibrations were transmitted from the piano. This has confirmed that our auditory system could be reached by sound over a different medium aside from our eardrums, which is our bones.
How Bone Conduction Allows People to Hear
Bone Conduction circumvents the eardrums. Listening through bone conduction, devices for bone conduction devices like headphones and smart glasses, does the responsibility of your eardrums. Sound waves are deciphered by these devices and change these waves into vibrations that could straightaway be received by the inner ear, hence the eardrum isn’t used. The “sound” goes to the ears in the form of vibrations via the bones and skin.
