The word sound can be used to describe auditory sensations that are neutral or pleasant, indicating the presence of vibrations perceived by the ears. It is often used in a general sense to explain anything that can be heard, whether it is music, speech, or environmental noises. Sound plays an essential role in communication, alert systems, and in the ambiance of environments.

The word noise is employed when discussing any unwanted or disruptive auditory stimuli that can be jarring or bothersome. It is also used to describe excessive sound that causes discomfort or a hindrance to concentration or communication. In the context of communication and audio technology, noise can refer to background interference or static that affects the clarity of signals.

While both sound and noise refer to auditory experiences, sound is an encompassing term for vibrations perceived by our ears. Noise specifically refers to sounds that are unwelcome, disruptive, or harmful. Sound can enrich environments and facilitate communication, whereas noise is often a source of irritation and is managed through various control methods. Understanding the distinction between sound and noise is crucial for fields such as acoustics, audio engineering, and environmental health.
