Nelson Exaust Silencers Attenuation Data

Attenuation Data

Nelson Silencers offer four attenuation ranges to provide the optimum performance for your application. Because of the particular characteristics of your application, performance levels are shown as bands of expected attenuation over a broad range. These curves are based upon "typical conditions. They will not necessarily define the exact insertion loss for a specific application since the insertion loss achieved is influenced by many factors, including engine size, type, speed, and unsilenced noise levels and frequency distribution.

100 Level | 200 Level | 300 Level | 400 Level

Note: Attenuation and back pressure curves are estimates only. Many variables exist that can affect actual performance for a specific application. Our liability is limited to replacement of product or to original price of product. We assume no liability for any costs associated with replacement or use of our product.
