LOUDNESS PERCEPTION Meaning and
Definition
-
Loudness perception refers to the subjective experience of how loud or soft a sound is to an individual. It is the perception of sound intensity or volume by the human auditory system. Loudness perception is influenced by various factors, including the physical characteristics of the sound source, the environment in which the sound is heard, and the individual's auditory sensitivity.
Sound intensity is measured objectively in decibels (dB), but loudness perception can vary between individuals. Factors that can affect the perception of loudness include the frequency or pitch of the sound, duration, and the individual's hearing ability. For example, higher frequency sounds may be perceived as louder than lower frequency sounds at the same intensity level.
The human ear is more sensitive to certain frequency ranges, particularly those between 2,000 and 4,000 Hz. This means that sounds within this range may be perceived as louder even at lower intensity levels compared to sounds outside this range. Additionally, the duration of a sound can influence its perceived loudness. Sounds that are shorter in duration are often perceived as less loud compared to longer sounds with the same intensity level.
Loudness perception is typically described using a logarithmic scale, known as the sone scale, which attempts to represent the non-linear relationship between physical sound intensity and perceived loudness. This scale enables researchers and audiologists to measure and describe loudness in more accurate and meaningful ways.
Overall, loudness perception is a complex process that encompasses various sensory and cognitive factors, resulting in the subjective experience of how loud or soft a sound is to an individual.

Etymology of LOUDNESS PERCEPTION
The etymology of the word "loudness" can be traced back to the Old English word "hlūd", which meant "noisy" or "clamorous". It originated from the Proto-Germanic word "hlūdaz". In Middle English, the term evolved to "loud" with similar meanings.
The word "perception" stems from the Latin word "perceptio", which means "the act of perceiving or comprehension". It comes from the verb "percipere" which combines "per" (through) and "capere" (to take).
The combination of these two words, "loudness perception", refers to the subjective experience or recognition of the quality and intensity of sound.
