Behavioural studies showing sensory attenuation have used tasks in which subjects generate a sound in the active condition and report perceived sound loudness relative to an externally generated reference sound (for example, refs 9, 38).
Science & Research
Since the mid-19th century, the Weber-Fechner law has been applied to human estimations of many physical sensations: weight, luminosity, sugar sweetness or sound loudness.
Science
The Smart Cities sensor board includes a linear displacement sensor for detecting cracks in building and infrastructures, a particle sensor for measuring air-suspended pollutants and a microphone for A-level weighted sound loudness.
Sound loudness was individually adjusted at the beginning of the scanning.
This is supported by our previous results suggesting neural sensitivity to sound loudness changes in these same 2-year-old children with RAOM [ 7].
Human voice is referred to as one of the bodily vital signs that could be measured, recorded, and analyzed as fluctuations of amplitude of sound loudness.

Beat finding requires detection of salient or "accented" events (e.g., bass/drum sounds, loudness changes, or long notes; Cooper and Meyer 1960; Povel and Okkerman 1981; Palmer and Krumhansl 1990).
Science
In order to prevent the listeners from sorting the sounds according to their loudnesses, a preliminary loudness-equalization experiment was conducted with 7 participants working at IRCAM, resulting in an 83-sound loudness-equalized corpus.
As a consequence, the sounds' loudnesses were equalized with regard to the value given by the loudness model of Zwicker and Fastl [24].
And for sound, pitch, loudness, and timbre define a tone.
News & Media
In place of conventional psychoacoustical models, the WT-NN technique is suggested not only to predict, classify, and compare the sound quality (loudness and sharpness) of vehicle interiors, but also to apply to other sound-related fields in engineering.
Expert writing Tips
Best practice
When describing the intensity of sound in a technical or scientific context, consider using more precise terms like "sound intensity" or "sound pressure level" instead of "sound loudness" for better clarity.
Common error
Avoid using "sound loudness" when "loudness" alone suffices, especially in informal contexts. While not grammatically incorrect, it can sometimes sound redundant.

Ludwig's WRAP-UP
In summary, "sound loudness" is a grammatically correct noun phrase used to describe the intensity or volume of sound. While understandable, it can sometimes be redundant, as "loudness" alone often suffices. Ludwig AI validates its usability. More formal alternatives such as "sound intensity" or "sound pressure level" are preferable in technical contexts. The phrase appears most frequently in scientific and news-related sources, indicating a neutral to formal register. When crafting your writing, consider the audience and context to determine whether "sound loudness" is the most precise and effective choice.

FAQs
How is "sound loudness" measured?
The loudness of sound is typically measured in decibels (dB) using a sound level meter. This measurement reflects the sound pressure level, which is related to how humans perceive loudness.
What is a more formal alternative to "sound loudness"?
More formal alternatives include "sound intensity" or "sound pressure level", which are technically defined terms used in acoustics and audio engineering.
Is there a difference between "sound loudness" and "volume"?
While often used interchangeably, "sound loudness" refers to the perceived intensity of a sound, whereas "volume" often refers to an adjustable setting on an audio device that controls the sound's output level.
When is it appropriate to use the phrase "sound loudness"?
It's appropriate when discussing the perceived intensity or volume of a sound, especially in contexts where you want to emphasize the subjective experience of loudness, such as in discussions of sensory perception or audio quality.
