DOI: 10.1016/j.jsv.2017.07.021
Abstract: Abstract Structurally radiated sound power is a critical design parameter. The acoustic radiation mode approach for computing sound power was developed in the early 1990s and has since been widely used. It has been shown… read more here.

DOI: 10.3390/app10010004
Abstract: When active noise control (ANC) is applied to acquire a ‘quiet zone’, it may produce an increase in the sound power outside the quiet zone and a change in the primary sound field, which are… read more here.
