what is loudness of sound ?
Answers
Answer:
Sound intensity, also known as acoustic intensity, is defined as the power carried by sound waves per unit area in a direction perpendicular to that area. The SI unit of intensity, which includes sound intensity, is the watt per square meter.

Answer:
In our everyday life, we come across different types of sounds like birdsong, animal sounds, airport sounds, etc. Our human brain is well-equipped with a mechanism to understand different types of variations in the sound pattern.
A man has a different sound compared to a woman. An adult has a different sound compared to the child and so on. Just like heat, electricity, or light, sound is also a type of energy. When a sound is made by something, it starts vibrating the air molecules, which sends a series of reactions through the air until it reaches our eardrums. As soon as our ears pick up any sound, signals are sent to our brain so that we can understand what we're hearing. Now the question arises what is loudness of sound?
Loudness is the property by which one can distinguish between two sounds of the same frequency and pitch. The loudness of sound is determined by the intensity and amplitude of the sound waves. Intensity can be measured by the amount of energy in sound waves. The loudness of sound is directly proportional to the square of the amplitude of vibration and If the amplitude of the sound wave is large, then the sound is said to be loud. In this topic, we have studied how to define loudness of sound. Since we have understood what is the loudness of sound, let’s discuss more on the difference between loudness and intensity of sound.
