AcuWood Report 3, SP Report 2014:16
This report presents the results from a questionnaire-based field survey and listening tests, both aiming to gain insight into the acoustic satisfaction of inhabitants of wooden buildings and to find objective acoustic descriptors, which correlate with subjective human perception of acoustic quality. In total 414 responses were collected in the questionnaire-based field survey. Field measurements and recordings in part of the buildings, which were involved in the questionnaire-based field survey, were conducted to derive acoustic descriptors, which are correlated to the subjective judgements.
The questionnaire-based field survey reveals that the overall ratings by the residents may be considered as very satisfying. Ratings with regard to annoyance caused by noise are quite low. However, walking noise caused by neighbours raises the highest complaint compared to other noise sources. It can also be shown that building and floor construction types differ with regard to perceived acoustic annoyance caused by walking noise. Ratings of residents in single-family houses differ from ratings of residents in multi-family houses. In this sample floor constructions made from wood are not rated worse compared to floor constructions made from concrete. However, this only holds true, if wood-concrete composite floors are included in the group of wooden floors. Within the group of floor constructions made from wood, the different types of floors clearly differ from each other with regard to perceived acoustic annoyance caused by walking noise. This result from the survey is in accordance to the listening tests and the measurement results in the building when using an appropriate single number descriptor. In general it can be stated that the questionnaire used in this field-survey may be applied for post occupancy evaluation and identification of construction problems in wooden buildings.
The listening tests reveal that the test persons perceive clear differences between the different floor constructions, floor coverings and noise sources. It can also be shown, that the annoyance ratings in the laboratory listening test match with the ratings of noise caused by walking neighbours in the questionnaire-based field survey, which justifies the development of an algorithm to predict acoustic annoyance caused by walking noise based on the laboratory measurement and listening test data accompanied by an evaluation in the field.
