Sound is the oscillation of pressure through a medium and is measured in decibels.
Sound is usually measured in Hertz.
The average 2 mw wind turbine produces a sound eqaul to 45 decibels
60 dB sound pressure level is about conversational speech listened in 1 meter distance.
The volume of a sound is measured by the sound pressure in pascals or newtons per square meter. The sound pressure level is measured by a sound pressure level meter (SPL meter).
Sound is the oscillation of pressure through a medium and is measured in decibels.
Maracas are percussion instruments that produce a relatively soft sound compared to other percussion instruments like drums or cymbals. The sound produced by maracas comes from the rattling of the beads or seeds inside the hollowed-out gourd or plastic shell. While they can vary in volume depending on how vigorously they are played, maracas are generally considered to produce a softer sound compared to louder instruments in the percussion family.

A subjective measure of sound is whether something is too loud, or too soft. A scientific measure of sound is gauged in the decibel level of the noise.
Maracas can produce a range of sound volumes depending on how vigorously they are shaken. The sound can be soft if shaken gently, or loud if shaken more aggressively.
soft
When you bang something soft the sound will be soft and when you bang something hard the sound will be loud.The same with talking, if you talk loudly the sound will be loud and when you talk quietly the sound will be soft.
SOFT
It determines how loud or soft the sound is.
volume
Soft sound of transportation could be the humming of an electric car, while a loud sound could be the engine noise of a motorcycle.
The measurement of how loud or soft a sound is called its amplitude or intensity. This is typically measured in decibels (dB).
