Laboratory acoustic measurements - Building and environment

After recalling the basics of the theory of sound production and propagation in a first article , we will apply these basic principles to the environment and buildings, studying laboratory measurements in this article [R 3 113] and in situ measurements in the following article. .

For definitions of the symbols, please refer to .

Laboratory measurements essentially concern products or systems, which we wish to qualify independently of their environment. Thus, laboratory testing differs from in situ testing in that the test conditions are theoretically perfectly controlled, making it possible to qualify a product rather than an entire structure.
