Typically with diesel gensets the low frequency sound power is all controlling, usually 125-500Hz. These frequencies, due to their long wavelength (1.47-2.72m), are extremely challenging to treat.
Our approach is to treat the canopy holistically, giving consideration to multiple noise paths and their comparative levels and frequencies, thereby allowing us to hone our treatment to best effect.
