Room to Room Vibration Tranmission

Architects and acoustic consultants struggle to accurately estimate the vibration reduction index for their building designs. ISO 10848 defines a method for measuring this, but it is a long, tedious and expensive process which is implemented by building two rooms and their junctions one by one, exciting the wall and measuring the flanking and direct noise. This process must be done for each building design. When the design changes or the desired results are not achieved, the structure must be demolished and built again from the beginning.

Simulating Brake Squeal Noise

Brake squeal is one of the most challenging problems that car manufacturers have today. It occurs as a result of the vibration of the brake components such as brake disc and brake pads and therefore it disturbs the driver and passengers. Furthermore, because of its complex nature it is hard to completely understand the causes ...

Multidisciplinary Solutions For Brake Squeal

Although engineers have started to use simulation software to test brake squeal, its complex nature usually requires more than one different software and discipline. This makes it difficult to transfer data from one software to another and to work in different environments. To address complex brake squeal in one environment, multidisciplinary solutions (MD) can be used. ...

Acoustic Simulation for Automotive and Heavy Equipment Industries

At present, noise quality is a crucial issue for automotive and heavy machinery manufacturers. In addition to the strict governmental regulations, it is important for automobiles to maintain the perception of quality in costumer’s mind. On the other hand, the sound of heavy machinery is a safety issue. Loud noises can make it harder for ...
