Title: 126 Alleviation of low frequency noise by the soundproof opening built in Helmholtz resonators
Abstract: The low frequency noise is not clearly defined but is generally taken to mean noise below a frequency of about 100 to 150Hz. Noise at frequencies below about 20Hz is sometimes referred to as infrasound and this type of noise presents even greater difficulties in its measurement and assessment. The objective of our study is to suggest practical means of reducing the low frequency noise emanating from the opening of soundproof houses. This paper describes an experimental study on the alleviation of low frequency noise by the opening built in Helmholtz resonators.
