Noise is a subjective judgment of sound that is related to auditory perception and can have a substantial impact on human health and well-being. The effects of noise on people include hearing loss, impaired growth and development in infants and children, general stress and sleep disruption, and decreased productivity/safety at work.

Physical damage to the ear can include a ruptured eardrum (usually at levels around 150 dB) or inner ear injury from sustained exposure to sounds over 85 decibels.

Next, I show you 5 strategies that will help you control noise:

Source Reduction: The fewer or smaller the noise sources, the lesser the impact. Although extending the distance between noise sources and receivers does not decrease sound, it is a typical noise reduction technique.

Sound blocking: Sound is reflected and/or absorbed by the barriers. Acoustic shadowing is a word often used to describe the effect of sound masking, especially in outdoor noise barriers.

Sound Absorption: Sound energy can be broken down into many small, separate vibrations. Good sound absorbers have widely varying surfaces that allow sound to penetrate the material, become “trapped” and dissipate (absorption).

Sound masking: If the background sound level rises within a defined range with a sound of specific quality (intensity, frequency, and absence of pattern), the initial sound source is “hidden” and the masking sound may remain discreet. Masking systems are most used in office buildings and hospitality establishments to address the unique challenge of speech intelligibility. Starbucks uses this strategy with great success.

Sound Cancellation: Because sound is a wave of energy, superimposing one sound source on top of another that is exactly 180 degrees out of phase cancels the original sound field.
