CONSIDERATIONS ON ACTIVE REDUCTION NOISE, TREATMENT AND CONTROL DESIGN PERFORMANCE AT DIESEL GENERATOR

Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2011, Vol 56, Issue 2

Abstract

This paper discusses the methodology and results of a noise audit and active control testing on a portable single-cylinder diesel generator. Using a large microphone array, a spectral intensity map of all external surfaces of the generator set was constructed from experimental measurements. Two primary noise sources were measured: a relatively directional high-frequency structurally-coupled engine component, and low-frequency fundamental exhaust firing-order harmonics. The lowfrequencies were reduced using the feed-forward Filtered-X LMS with a reference derived directly from the electrical generator coupled to the diesel engine.
