Good “sound quality” is paramount for consumer products. The device should make appropriate sounds that please and inform the user, and suggest quality, power, value, etc.
The process is straightforward:
- Evaluate current noise emission (for existing products)
- Estimate noise emission (at the drawing board stage)
- Identify objectionable characteristics
- Determine sound quality goals
- Recommend design changes for immediate improvement
- Introduce long-term best-practice design practices that support the SQ goals.
- Make the noise reduction intrinsic, with minimum reliance on treatments that add cost, parts count, weight, complexity ,etc.
- Establish target noise levels and sound quality characteristics for retail refrigeration equipment
- Develop proprietary sound quality metrics for personal computer sounds
