Abstract
The low frequency noise is not clearly defined but is generally taken to mean noise below a frequency of about 100 Hz. Noise at frequencies below about 20 Hz is sometimes referred to as infrasound and this type of noise presents even greater difficulties in its measurement and assessment. The objective of our research is to suggest practical means of reducing the low frequency noise emanating from the opening of soundproof houses. This paper describes an experimental research on the alleviation of low frequency noise by the filtered-x LMS active noise control in a subscale model house.
