Noise Atmospheric noise or static is caused by lighting discharges in thunderstorms and other natural electrical disturbances occurring in the atmosphere. These electrical impulses are random in nature. Hence the energy is spread over the complete frequency spectrum used for radio communication.

Noise Level Chart Noise Level Chart. A noise level chart showing examples of sounds with dB levels ranging from 0 to 180 decibels. Most noise levels are given in dBA, which are decibels adjusted to reflect the ear's response to different frequencies of sound. Sudden, brief impulse sounds, like many of those shown at 120 dB or greater, are often given in dB (no adjustment).

sound sound. 1. a pressure wave propagating through an elastic medium; waves with a frequency of 20–20,000 Hz cause the sensation of hearing. 2. the effect produced on the organ of hearing by vibrations of the air or other medium.

Noise sensitivity Noise sensitivity. The range of sound we can hear is phenomenal; some people can literally hear a pin drop and yet most can still tolerate loud sounds such as heavy machinery. Hyperacusis is an unusually low tolerance to ordinary environmental sounds, which are tolerable to listeners with normal hearing.

NOISE NOISE: Noise, one of the more irritable factors which can ruin a countryside, according to some research, however, the line between noise, music and 'non-noise' is still blurred. In terms of devices, noise refers to radio waves which are emitted by other devices such as TVs or phones which can disrupt internet routers for example.

Understanding Transformer Noise: Transformer Noise Factor. Understanding Transformer Noise: Noise is defined as unwanted sound. Transformer humming has been known to soothe people but generally it is thought to be a nuisance. The causes and reduction of transformer noise has come to prominence again.

sound sound 1. 1. A type of wave motion that originates as the vibration of a medium (such as a person's vocal cords or a guitar string) and travels through gases, liquids, and elastic solids as variations of pressure and density. The loudness of a sound depends on the amplitude of the sound wave.

Mimicry In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a medium such as air or water.

What is the definition of sound energy? Acoustic energy is sound energy produced by vibrating objects. The definition of sound says that it is a disturbance of energy that comes through matter as a wave, and that humans perceive sound by the sense of hearing. Sound pressure is the effect and sound power (energy) is the cause. But our eardrums are only sensitive to the sound pressure, and so are microphone diaphragms.

- sound wave. Share this item with your network: A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water, or any other liquid or solid matter) as it propagates away from the source of the sound. The source is some object that causes a vibration, such as a ringing telephone, or a person's vocal chords.

Sound In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a transmission medium such as air or water. In physiology and psychology, sound is the reception of such waves and their perception by the brain.

Communication noise Semantic noise. This is noise caused by the sender. i.e., the encoder. This type of noise occurs when grammar or technical language is used that the receiver (the decoder) cannot understand, or cannot understand it clearly.

What is SOUND? What is SOUND? The periodic mechanical vibrations and waves in gases, liquids and solid elastic media. Specifically the sensation felt when the eardrum is acted upon by air vibrations within a limited frequency range, ie 20 Hz to 20 kHz. Sound of a frequency below 20 Hz is called infra. STRUCTURE-BORNE SOUND.

sound 1 Sound and noise are often used interchangeably for anything perceived by means of hearing. Sound, however, is more general in application, being used for anything within earshot: the sound of running water. Noise, caused by irregular vibrations, is more properly applied to a loud, discordant, or unpleasant sound: the noise of shouting. Tone is applied to a musical sound having a certain quality, resonance, and pitch.

Sound Sound can also mean a body of water, like a bay or channel. We can define a sound wave as a disturbance which travels through some medium. Sound is the term to describe what is heard when sound waves pass through a medium to the ear. All sounds are made by vibrations of molecules through which the sound travels. For instance, when a drum or a cymbal is struck, the object vibrates. These vibrations make air molecules move.

- Sound level or noise level is a physical quantity measured with measuring instruments. Loudness is a psycho-physical sensation perceived by the human auditory perception or the human ear/brain mechanism. That is not the same.

Colors of noise Black noise is also called silent noise. 1  Silence. 2  Noise with a 1/fβ spectrum, where β > 2. This formula is used to model the frequency of natural disasters. 3  Noise that has a frequency spectrum of predominantly zero power level over all frequencies except for a few narrow bands or spikes.

- 21 7. Device noise profiles A device noise profile (or noise profile, or simply profile) describes the properties of noise produced by an imaging device (e.g., digital camera, scanner, etc.) working in a certain mode. Several noise profiles corresponding to different modes of a device constitute a profile set.ser Guide Neat Image plug-in for Photoshop (Win) 14 © 1999-2014 by Neat Image team, ABSoft.
