Sound barriers are custom acoustic insulation that blocks sounds instead of absorbing or damping them. They’re made of dense materials and are used at the source of a sound and along its path. To choose the right noise control product, engineers need to understand how sound barriers work, how they’re made, and the different types that are available. Continue reading Sound Barriers for Noise Control
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 Noise Control and Acoustic Insulation: Sound Sources and Frequencies
Acoustic insulation absorbs, transmits, or redirects sound – a form of energy that travels in waves. Some sounds are pleasant to hear, but others can harm human health, endanger workers, or contribute to structural fatigue. Undesirable sounds, or noise, have characteristics that designers of acoustic insulation need to understand. Without this knowledge, noise problems can cause design-related headaches.
In Part 1 of this series from Elasto Proxy, you’ll learn about the consequences of noise and discover why its characteristics might not be what you think. You’ll also consider why decibel-level differences in noise sources matter. Then, in Part 2, we’ll examine sound measurements and noise control in greater detail. Along the way, we invite you to contact us with your questions about acoustic insulation. Continue reading Acoustic Insulation: What You Need to Know About Noise
