Case Studies
Washing Machine Noise
An appliance manufactures product was significantly louder than their competitors, hampering efforts to move into a very competitive foreign market. AES, in conjunction with the Acoustic Research Group at the University of Canterbury, were engaged to undertake an extensive research and development project to develop a quieter machine. This work had to start at the very core of the problem, looking in detail at the noise sources in the machine, and how this noise was transmitted to the listener. Read more
Design of a Traffic Noise Barrier
The developers of a new subdivision were concerned about potential reverse-sensitivity problems due to noise from a near-by State Highway. AES were engaged to design a traffic noise barrier which would provide sufficient traffic noise attenuation so as to minimise the need to acoustically upgrade dwellings in the subdivision, and to maximize the area of the subdivision in which the sound levels due to traffic complied with outdoor levels recommended by the World Health Organisation.
