Abstract:

As manufacturers are exploring ways to make their products “sound,” more attractive product sound quality testing is becoming popular in the industry. The automotive industry is one of the leaders in product sound quality testing and this has led to the development of sophisticated tools designed to test sound quality in the passenger seat of a car. One of those tools is the Head Acoustics measurement system. This system includes an artificial head mounted on an artificial torso. The torso height is scaled such that it fits into a car seat just as its human counterpart would. In fact, the torso even comes with attachment points for seat belts. Within each “ear” are Type I microphones attached to a binaural equalization system designed to mimic the frequency response of the human ear Using this measurement system, sound quality tests were conducted on various on-road vehicles. The vehicles ranged from an old pickup truck with a bad muffler to a relatively new Jaguar X-Type. An Alfa Romeo was sought after for testing, however, the authors could not find any in running condition. Overall, fifteen vehicles were tested and the results of various sound quality measurements are described in this paper.
