This may be defined as the rate of sound energy transmitted in aspecified direction per unit area normal to the direction. With goodhearing the range is from about 0.000000000001 Watt per square metreto about 1 Watt per square metre (12 orders of magnitude greater). Thesound intensity level is found from intensity I (W/m^2) by: Sound…

It is best, where possible, to avoid any unprotected exposureto sound pressure levels above 100dB(A). Use hearing protection whenexposed to levels above 85dB(A), especially if prolonged exposure isexpected. Damage to hearing from loud noise is cumulative and isirreversible. Exposure to high noise levels is also one of the maincauses of tinnitus. The safety aspects of…

The eardrum is connected by three small jointed bones in the air-filledmiddle ear to the oval window of the inner ear or cochlea, a fluid-filled spiral coil about one and a half inches in length. Over 10,000hair cells on the basilar membrane along the cochlea convert minusculemovements to nerve impulses, which are transmitted by the…

If there are two sound sources in a room – for example a radioproducing an average sound level of 62.0 dB, and a television producinga sound level of 73.0 dB – then the total sound level is a logarithmicsum ie Combined sound level = 10 x lg ( 10^(62/10) + 10^(73/10) ) = 73.3 dB…

Noise was not of particular concern at the beginning of the century.The first electrical sound meter was reported by George W Pierce inProceedings of the American Academy of Arts and Sciences, v 43 (1907-8)A couple of decades later the switch from horse-drawn vehicles toautomobiles in cities led to large changes in the background noiseclimate. The…

Ans. It is an extensive field; you can get numerous job opportunities after graduation.

Regenerative braking is a technology that converts kinetic energy into electrical energy during braking, which is then used to charge the battery in hybrid and electric vehicles.

In a front-wheel-drive vehicle, power is transmitted to the front wheels, while in a rear-wheel-drive vehicle, power is transmitted to the rear wheels.

Electronics play a vital role in modern automobiles by controlling engine functions, managing safety systems, supporting infotainment features, and enhancing vehicle performance.
