Abstract:
In the evaluation of 750 OEM Autosound systems Tom Nousaine, Listening Technology, has found that a majority of systems suffer from spectral uniformity problems at low frequencies. This simply means that bass sounds are uneven. For example on a program with an acoustic bass solo, some notes almost disappear while others may seem unusually loud. It is commonly felt that this is a simple equalization issue. Thus, it is puzzling that this problem continues to exist when modern car electronics have significant active sound control capabilities. The panel will discuss the issue, causes, and possible solutions.
