A deep-learning-based acoustic eigenvalue analysis method is proposed for predicting the
acoustic natural modes and natural frequencies of a double cavity such as a passenger …

A systematic design process for an optimal suction muffler is proposed to reduce the noise of
a reciprocating compressor. Because the outer shape of a suction muffler is complicated, the …

This study presents a forced acoustic analysis and investigation of the energy distribution of
a theoretical model of coupled rooms with a transparent coupling aperture. The energy …

It is very important to predict the acoustic radiation of vehicle body for the control of interior
noise. Firstly, the kinetic equations of coupled acoustic-structural finite element method are …

When two acoustic cavities are connected through an opening, the acoustical characteristics
of the resulting double cavity can be considerably affected by the opening. Typical examples …

The parcel shelf of a car has several holes for speakers and electrical devices. In addition,
air ventilation holes are installed on the trim that covers the parcel shelf. The effect of the …

The effects of additional cavities and air-gaps in the acoustic response of a passenger
vehicle are investigated. It is observed that the cabin cavity and the trunk cavity of the …

The ubiquitous presence of noise in modern societies causes a significant amount of
psychological strain and stress in individuals, and since this is especially true for …

The position and size of holes in the partition of a double cavity are known to strongly affect
the eigenfrequency of the longitudinal eigenmodes of the double cavity. To maximize or …

Reduction of Heating, Ventilation and Air Conditioning (HVAC) systems and other
components such as engine and exhaust system has resulted the study on the vehicle noise …
