Noise reduction is a broadly used term and sometimes not very clear. Noise. Difficult stuff also. Sound power or sound pressure? What exactly is the main source? Tolerances? Distance reductions, directivity, logarithmic scales? But sometimes questions are very clear. Like some years ago when we were ask to make a copy of an existing silencer, but then in a version that would actually meet the requirements. The existing one didn’ t. Well we do like a challenge! So we designed a version with TIO internals. And of course this post would not be here if we did not succeed. Begin this year we again supplied a serie of these silencers. If you need a silencer that meets the noise requirements; feel free to contact us!
