The attri only ife of move by which a shrill sound can be distinguished from a grave sound is known as PITCH. haggle of sound depends upon the frequency of sound. The greater the frequency, the higher is the careen and vice versa. It is the slant of sounds that enable us to distinguished b/w a sound of man and woman or man and red hot. Etc. sound of a woman is shrill due to high flip. Sound of a dog is grave due to low tack and low frequency.QUALITY OR prizeThe straitlacedty of sound by virtue of which we can distinguish amid two sounds of the same pitch and the loudness originating from two different musical instruments. The sound produced by two different instruments is usually complex. It is a mixed bag of several tones. The tone of lowest frequency is called Fundamental frequency and new(prenominal) tones are known as OVERTONES OR HARMONICS. The loudness of sound depends upon the premium of vibration. And pitch determined by its fundamental frequency. Two or to a gr eater extent sound may have the same loudness and the same pitch but that they may differ in number and relative intensities of overtones. The quality of sound depends upon the wave from of the resultants. Nature has much(prenominal)(prenominal) a great mutation that it is very rare to have some overtones of two persons exactly. So this going away is overtones makes it possible to recognize each sound. This characteristic of sound is called QUALITY. INTENSITY OF belongThe intensity of sound is defined as the amount of energy contagious per second through unit area held perpendicularly in the caution of sound waves. Intensity of sound = E/t.A OR I = E/t.A Pitch Pitch = frequency of soundFor example, middle C in compeer temperament = 261.6 HzSounds may be generally characterized by pitch, loudness, and quality. The sensed pitch of a sound is just the ears response to frequency, i.e., for most practical purposes the pitch is just the frequency. The pitch perception of the human ear is understood to hold basically by the place possible action, with some sharpening mechanism necessary to formulate the remarkably high resolution of human pitch perception. The place theory and its refinements provide plausible models for the perception of the relative pitch of two tones, but do not explain the phenomenon of perfect pitch. The just noticeable residuum in pitch is conveniently expressed in cents, and the standard formula for the human ear is 5 cents.Sound quality is typically an assessment of the truth, enjoyability, or intelligibility of sound recording output from an electronic thingamajig. Quality can be careful objectively, such as when tools are used to gauge the accuracy with which the device reproduces an original sound or it can be measured subjectively, such as when human listeners respond to the sound or gauge its sensed similarity to another sound. The sound quality of a reproduction or recording depends on a number of factors, including the equipment used to make it, touch and mastering done to the recording, the equipment used to reproduce it, as well as the listening environment used to reproduce it.In some cases, bear on such as equalization, dynamic range compression or stereo processing may be applied to a recording to create audio that is significantly different from the original but may be perceived as more agreeable to a listener. In other cases, the goal may be to reproduce audio as closely as possible to the original. When applied to specific electronic devices, such as loudspeakers, microphones, amplifiers or headphones sound quality usually refers to accuracy, with higher quality devices providing higher accuracy reproduction. When applied to processing steps such as mastering recordings, irresponsible accuracy may be secondary to artistic or aesthetical concerns. In still other situations, such as recording a live musical performance, audio quality may refer to proper placement of microphones around a agency to optimally use room acoustics.
