• Noise Vs. Sound

    What is Sound?

    Sound is produced by vibrating objects and reaches the listener's ears as waves in the air or other media. When an object vibrates, it causes slight changes in air pressure. These air pressure changes travel through the air and produce sound waves.

    What is Noise?

    Sound is what we hear. Noise is simply unwanted sound.

    The difference between sound and noise depends upon the listener and the circumstances. Rock music can be pleasurable sound to one person and an annoying noise to another. In either case, it can be hazardous to a person's hearing if the sound is loud and if he or she is exposed long and often enough.

    Noise is one of the most common occupational health hazards. In heavy industrial and manufacturing environments, as well as in farms, cafeterias, permanent hearing loss is the main health concern. On a typical, day-to-day basis, annoyance, stress and interference with speech communication are among the most common issues resulting from unwanted noise.

    How to Combat Noise

    To prevent adverse outcomes of noise exposure, noise levels should be reduced to acceptable levels. The best method of noise reduction is to use engineering modifications to the noise source itself, or to the workplace environment.
