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…

Abstract: Abstract Breakout noise is prominent at low frequencies in a rectangular shaped duct due to strong structural–acoustic coupling and is characterized in terms of transverse transmission loss (TTL). The main objective of the present investigation…

Abstract: In order to determine the radiated sound power of an underwater source below the Schroeder cut-off frequency in a non-anechoic tank, a low-frequency extension measuring technique is proposed. This technique is based on a unique…

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…

Abstract: Airborne port noise has historically suffered from a lack of regulatory assessment compared to other transport infrastructures. This has led to several complaints from citizens living in the urban areas surrounding ports, which is a…
