An assessment of automotive sound quality

A psychoacoustic approach for sound quality assessment of automotive power windows

Psychoacoustic methodologies were investigated and applied to a case study within a cooperation project of the University of Pisa and Magna Closures S.p.A. mainly focused on the acoustics of power windows. The project included tests on closing-opening event sequences of the power window rail, to evaluate the component noise. Different trials were performed varying the test conditions. Time-freq...

Sound Quality of Turn Indicator Sounds—Use of a Multidimensional Approach in the Automotive Product Development

Vehicle sounds are important factors of customer satisfaction and have a decisive influence on the product automobile and its quality impression. It becomes more and more important to connect customer requirements and technical specifications to develop a vehicle sound with high quality. The turn indicator sound can be described as one sound, which gives the customer an important feedback of co...

Improving the Effectiveness of Paired Comparison Tests for Automotive Sound Quality

Sounds generated by new vehicles are important for brand identification and product differentiation. Consequently automotive manufacturers are interested in how to turn customer preferences of sounds into achievable engineering targets; sound quality engineering. One tool within this process is paired comparison testing, where a jury is asked to choose between pairs of sounds given a particular...

Assessment and improvement of sound quality in cochlear implant users

OBJECTIVES Cochlear implants (CIs) have successfully provided speech perception to individuals with sensorineural hearing loss. Recent research has focused on more challenging acoustic stimuli such as music and voice emotion. The purpose of this review is to evaluate and describe sound quality in CI users with the purposes of summarizing novel findings and crucial information about how CI users...
