Sound waves do not have a mass of their own. Mass is a property of physical objects, whereas sound waves are disturbances or variations in a medium, typically air, caused by the vibration of objects. Thus, it is not meaningful to measure the mass of a sound wave itself.
However, the objects or sources that produce sound waves can have mass. For example, a vibrating loudspeaker or a musical instrument has mass. In such cases, the mass of the object itself can be measured using various methods appropriate for the object in question, such as weighing it on a scale or using specialized instruments like a balance.
When we perceive sound, we are detecting the vibrations caused by the sound waves interacting with our ears. These vibrations are converted into electrical signals that are then processed by our brain, allowing us to perceive sound. It is important to note that the sensation of sound is not directly related to the mass of the sound waves but rather to their frequency, intensity, and other characteristics.
