Noise produced by a vertical bow, cross bow, air gun or hunting clothing is of significant interest to a hunter. However, until now there has been no engineering resource with the test lab capabilities needed to characterize and dissect the contribution of a vibrating limb, riser, arrow rest or string in bow; the noise characteristics of an air gun; or the sliding of fabric against itself, another fabric, or accessory to the audible noise signature they produce. Stress Outdoor® developed and constructed a noise and vibration testing facility to help manufacturers quantify the frequency and magnitude of the noise produced by hunting products.
