Initially a simple postal questionnaire was carried out in order to establish the perceived relevance of sound quality assessment in a variety of industries. Questionnaires were sent to one hundred UK based manufacturers of a wide variety of different types of products.
The types of product included in the survey, and the categories used to display the results are listed below:
|Outdoor Equipment||Domestic Appliances and White Goods||Heating and water||Home entertainment|

Extractor hood for oven, small kitchen appliances e.g. juicer, ice-cream makers, steamer, slow cooker, fryer, can opener, bread maker, kettle, food processor, whisk, food mixer/blender, coffee maker, etc.

Forty seven questionnaires were received from companies, in all of the categories listed above, though not all of the specific types of product were covered by the replies. One of the questionnaires was incomplete and so the results from this have not been included. Two companies sent two completed questionnaires from different employees, and one manufacturer sent three completed questionnaires from different employees, since the replies in each case were slightly different, none of these questionnaires have been removed from the results.
