Our ear drums are moved by the sound pressure. The sound pressure as sound field quantity is measured in pascals or newtons per square meters.
Forget the sound intensity (acoustic intensity) as sound power quantity. Only noise fighters need that or if you measure earthquakes.
This answer is very good, but, it needs a little bit more information the answer was mostly talking about eardrums so, we would need an answer talking about the topic.
when a sound enters the ear canal it travels in and then the sound hits the eardrum and vibrates to make you hear the sound clearly. Then it fianlly it may pass by the anvil.
Intensity
Sound intensity is measured in watts per square meters, but our eardrums are only moved by the sound pressure measured in newtons per square meters or pascals.
Heat intensity (how Hot is it) is measured by the objects Temperature in Degrees, Fahrenheit, Centigrade, or Kelvin. Heat content (energy) is most commonly measured in Calories.
No.. hertz relates to the frequency (pitch). The volume of a sound is measured in decibels.
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).
decibels
Relative intensity is measured in decibels and is abbreviated dB.
Intensity
Intensity can be measured by converting units of electrical power in to decibels.
The intensity of vibrations is typically measured in units called decibels (dB) for sound vibrations, or in units such as meters per second squared (m/s^2) for mechanical vibrations.
Decibels
Sound intensity I is measured in watts per meter squared (W/m²). Look at the link: "Conversion of sound units (levels)".
units of time
units of time.
Intensity refers to the amount of energy in a sound wave, measured in watts per square meter, while loudness is the perception of intensity by the human ear, measured in units called decibels. Intensity can be objectively measured, while loudness is a subjective perception that can vary from person to person.
Luminous intensity is a scalar quantity, as it only has magnitude (brightness) and no direction associated with it. It is typically measured in units of candela.
Intensity of light is measured in units called lux (lx). Lux is defined as the amount of light intensity or luminous flux per unit area. It helps quantify the level of brightness perceived by the human eye.
