The actual intensity of sound refers to the amount of energy that is transmitted through sound waves. It is typically measured in decibels (dB) and is a quantitative measure of the loudness of a sound.
Perceived loudness is a subjective experience and can vary from person to person. Actual intensity, on the other hand, is a measurable physical quantity and does not depend on individual perception.
The actual intensity of a sound can be influenced by various factors such as the distance between the source of the sound and the listener, the characteristics of the medium through which the sound travels, and the power of the sound source.
The frequency of a sound refers to the number of cycles of vibration per second and is measured in Hertz (Hz). Higher frequency sounds typically have a higher actual intensity compared to lower frequency sounds at the same amplitude.
The actual intensity of a sound is typically measured using a sound level meter. This device measures the pressure variations in the air caused by sound waves and converts it into decibels. Other methods of measuring actual intensity include using a microphone and a computer-based software program.
