Sound level is a measure of the intensity of sound, typically expressed in decibels (dB). It is used to quantify how loud a sound is perceived to be by the human ear. Different sound levels can have varying effects on human health and well-being.
The measure of the loudness or intensity of sound is called decibels (dB). It quantifies the level of sound pressure that is perceived by the human ear. The higher the decibel level, the louder the sound.
The loudness of a sound is measured in decibels (dB). The higher the dB level, the louder the sound. Sound level meters are commonly used tools to measure the intensity of sound. Humans perceive louder sounds as being louder due to the amplitude of the sound waves.
Reference sound intensity Io = 10^−12 W/m² (Threshold of human hearing). Reference sound intensity level LIo = 0 dB-SIL (Threshold of human hearing intensity level). Sound intensity is a sound energy quantity. Our eardrums are moved by sound pressure variations. That is a sound field quantity. Reference sound pressure po = 20 µPa = 2×10^−5 Pa (Threshold of human hearing). Reference sound pressure level Lpo = 0 dB-SPL (Threshold of human sound pressure hearing level).
Sound power level refers to the total amount of sound energy produced by a source, measured in watts. Sound pressure level, on the other hand, measures the intensity of sound waves at a specific point, typically in decibels. In the context of measuring sound intensity, sound power level is the source of the sound, while sound pressure level is the measurement of how loud the sound is at a particular location. The two are related in that sound power level influences sound pressure level, but they are distinct measurements that provide different information about the sound being produced.
What is the maximum sound level is safe for human ear
Sound level is a measure of the intensity of sound, typically expressed in decibels (dB). It is used to quantify how loud a sound is perceived to be by the human ear. Different sound levels can have varying effects on human health and well-being.
Usually sound pressure level (SPL) in decibels (dB) is meant. A sound level meter is an instrument which measures the sound pressure level. The reading from a sound pressure level meter (SPL meter) does not correlate well to human-perceived loudness.

Reference sound intensity Io = 10^−12 W/m² (Threshold of human hearing). Reference sound intensity level LIo = 0 dB-SIL (Threshold of human hearing intensity level). Sound intensity is measured in watts per meter squared (W/m²) Sound intensity level is measured in decibels (dB). Sound intensity is a sound energy quantity. Our eardrums are moved by sound pressure variations. That is a sound field quantity. Reference sound pressure po = 20 µPa = 2×10^−5 Pa (Threshold of human hearing). Reference sound pressure level Lpo = 0 dB-SPL (Threshold of human hearing sound pressure level). Sound pressure is measured in pascals (Pa) or in newtons per meter squared (N/m²). Sound pressure level is measured in decibels (dB). Sound pressure is a sound field quantity.

They actually call 'human being' but there sound was like 'human beans'

The minimum of sound intensity can be theoretically as low as zero decibels. But you seem to mean what the human threshold of hearing is. That reference sound intensity is 10^−12 W/m² equal to 0 dB sound intensity level. Our eardrums are moved by the sound pressure. The reference sound pressure at the human threshold of hearing is po = 20 µPa equal to 0 dB sound pressure level (SPL).
Being creatures of acute hearing sense, they particularly hate high intensity sounds that are beyond the hearing level of the human ear. Supersonic sound emitters can accomodate this.
Reference sound intensity Io = 10^−12 W/m² (Threshold of human hearing). Reference sound intensity level LIo = 0 dB-SIL (Threshold of human hearing intensity level). The sound intensity I is measured in watts per meter squared. The sound intensity LI level is measured in decibels (dB).
