HOW TO IMPROVE ACOUSTICS IN YOUR METAL BUILDING
Acoustics, the science of sound transmission, is not a difficult subject metal roofing machine prices if you think of sound as a spherical wave that emanates outward from the source rather like a 3D dart target. You can imagine the waves as they radiate outward until they hit an object and, with a little knowledge of physics, how that wave will be impacted by specific materials. You can use this knowledge of acoustical properties to control where the sound goes, where it stops, how it reflects, and whether it becomes noise. Metal buildings are actually easy to handle acoustically with the right materials and tools. A QUICK GLOSSARY OF TERMS Noise: Unwanted sound Frequency: also known as pitch; measures how high or low a sound is. Wavelength: the distance between the beginning of one sound cycle and the beginning of the next. Amplitude: loudness Decibel: a measure of sound. Human hearing ranges z c roll forming machine from a whisper at 20 dB to pain at 120 dB; typical
