What is NoiseSimply stated, noise is unwanted sound. Intrusive sound that interferes with speech intelligibility or speech privacy is characterized as noise. Noise is a relative term and can range from low levels of intrusive sound in a quiet environment to very loud sounds in a already noisy environment. |
