Acoustic insulation absorbs, transmits, or redirects sound – a form of energy that travels in waves. Unwanted sounds, or noise, aren’t just unpleasant to hear. They can harm human health, jeopardize worker safety, and contribute to structural fatigue. The consequences of noise can be severe, but its characteristics are sometimes misunderstood.
In Part 1 of this series, Elasto Proxy shared a surprising example of two machines running at different decibel (dB) levels in the same room. In Part 2, we’ll examine some other sources of noise in the industries we serve. Importantly, you’ll learn why acoustic insulation must account for more than just a sound’s source. Frequency, the speed of the change of the sound, is a key design consideration for noise control. Continue reading
