Final answer:
The two definitions of sound are auditory perception and physical properties. The former is what we experience through hearing, while the latter refers to the objective characteristics of sound waves like frequency and amplitude.
Step-by-step explanation:
There are two definitions of sound, auditory perception and physical properties. The former refers to what we experience when we hear sounds, such as speech and music, while the latter refers to the physical properties of sound waves. Auditory perception is essentially our subjective experience of sound, which includes aspects like pitch, loudness, and tone. On the other hand, the physical properties of sound waves include aspects such as frequency, wavelength, amplitude, and the speed of the waves as they travel through different mediums.
Sound is a disturbance of matter that is transmitted from its source outward. It is one type of wave that we can relate to the basic properties of any wave. In the context of teaching and learning, exploring the properties of sound waves can help us understand the principles of acoustics and how these properties relate to our experiences with hearing.
