The attached file is the notes from the Attendees were placed on one of five tables (raw transducers, home/studio systems, automotive systems, professional audio systems, microspeakers and headphones) based on market segment. This is the results from the AUTOMOTIVE SYSTEMS table.

the group addressed the following questions:

1.How do you Evaluate System/Speaker Performance? This would focus on what data is measured and how. For example: frequency response, Impedance, Phase, Polar Pattern, sensitivity, and so on.
2.What data do you publish? This would cover not only the data published but also how it is displayed - smoothing, resolution, x/y format and axis labeling, and so on. Another aspect of this is what data do you not publish and why?
3.How do you correlate the measured data to your customer’s requirements and/or satisfaction? How do we inform professional customers and consumers that these data sets are useful, what they infer in terms of sound quality, what they mean in terms of selecting appropriate amplifiers, etc?
4.How do you insure that you duplicate this performance long term with EOL testing? i.e. How do you choose limits that maintain the integrity of the design, just avoiding audible or audibly distracting faults?
