The human ear is not the world's best sound receptor, although it does all right (if you take care of them). ... Much of what makes up the quality of sound produced by an instrument depends on how well it can transfer sound energy into the air. We've all heard of these fabulous old violins from Italy - the best known are the Stradivarius ...
Sound produced by humans | Class 8, Sound
Human speech is produced by complex interactions between the diaphragm, lungs, throat, mouth and nasal cavity. The processes which control speech production are phonation, resonation and articulation. Phonation. is the process of converting air pressure into sound via the vocal folds, or vocal cords as they are commonly called. Resonation

Any object that vibrates will produce sound. Human hearing has a frequency response of 20 – 20,000 Hz. Frequencies below audibility are called infrasonic and those above audibility are called ultrasonic.. Sound is a longitudinal wave and propagates in the air as pressure variations of the air molecules.

Sound is a form of energy, produced by rapidly vibrating objects, that can be heard by the human ear. Sound is a longitudinal wave. Most young people respond to sound frequencies of between 20 Hz and 20 000 Hz. Infrasonic- any sound with a frequency lower than 20Hz. Ultrasonic - any sound with a frequency above 20 000 Hz. How is Sound Produced ...

Using this relative intensity scale the range of human hearing is from 0 bels to approximately 12 bels. This was modified so that the basic unit became the decibel (db) which is 1/10 of a bel. Loudness is the name we use the describe the psychological sensation produced by the intensity of the sound.

The prevalence of human produced noise in our coastal waters, and its effect on marine-mammals and fish, are topics of growing public concern in British Columbia. Many groups, including environmentalists, fishermen, whale-watch tour operators and First Nations, all have, for various reasons, an interest in protecting our oceans from the effects ...
