A subjective term for the sensation of the intensity of a sound While intensity is a primary factor in the perception of loudness, it also is affected by frequency and duration of the stimulus
An equalization circuit used in some head units that progressively emphasizes low frequencies and sometimes high frequencies as volume is reduced; can be switchable (on, off), adjustable or automatic
The subjective sensation of the effect of amplitude or intensity It is determined partly by the number of auditory nerve fibers activated by the sound wave and partly by the number of impulses carried by each fiber The unit of measurement of subjective loudness is the sone
Physiological measure of amplitude of a sound wave; heard loudness depends on the pitch and tone color as well as amplitude
The loudness function boosts low frequencies, usually most useful at low volume levels
The amount of sound perceived by a listener; a perceptual quantity that can only be assessed with an auditory system
Perceived volume Loudness can be deceiving For example, adding distortion will make a given volume level seem louder than it actually is
Subjective sensation of the effect of amplitude or intensity It is determined partly by the number of auditory nerve fibers activated by the sound wave and partly by the number of impulses carried by each fiber The unit of measurement of subjective loudness is the "sone "
A listener's auditory impression of the strength of a sound The average deviation above and below the static value due to sound wave is called sound pressure The energy expended during the sound wave vibration is called intensity and is measured in intensity units Loudness is the physical resonance to sound pressure and intensity
The sensation that depends principally on the intensity of sound waves reaching the ear
the magnitude of sound (usually in a specified direction); "the kids played their music at full volume"
= The subjective judgment of intensity of a sound by humans Loudness depends upon the sound pressure and frequency of the stimulus Over much of the frequency range it takes about a threefold increase in sound pressure (a tenfold increase in acoustical energy, or, 10 dB) to produce a doubling of loudness
The human ranking of an auditory sensation, usually in terms ranging from soft to loud, expressed in sones (not in deciBels)
Attribute of auditory sensation corresponding to intensity Sounds can be ordered on a loudness scale from quiet to loud
{i} condition or quality of being loud; noisiness; vociferousness; vulgarity, poor taste
- Boosts the very high and very low frequency sounds at lower volume levels to give a natural sound balance
