There are several types of CLT constructions which are commercially available in Canada, but this study only focused on CLT panels that have adhesive between the faces of the timber elements in adjacent layers, but no adhesive bonding the adjacent timber elements within a given layer. There were noticeable gaps (up to 3 mm wide) between some of the timber elements comprising each layer of the CLT assembly. These CLT panels could be called "Face-Laminated CLT Panels" but are simply referred to as CLT panels in this Report. Another form of CLT panels has adhesive between the faces of the timber elements in adjacent layers as well as adhesive to bond the adjacent timber elements within a given layer. These are referred to as "Fully-Bonded CLT Panels" in this Report. Because fully-bonded CLT panels have different properties than face-laminated CLT panels, the sound transmission data and predictions in this Report do not apply to fully-bonded CLT panels.}, language = {en} } @article{HoellerGibbs, author = {H{\"o}ller, Christoph and Gibbs, Barry M.}, title = {Inverse Method to Obtain Blocked Forces of Vibrating Sound Sources in Buildings}, series = {Acta Acustica united with Acustica}, volume = {103}, journal = {Acta Acustica united with Acustica}, number = {4}, publisher = {ingenta}, doi = {10.3813/AAA.919092}, pages = {639 -- 649}, abstract = {Vibrating sources, such as building service equipment, are major contributors to noise in buildings. In order to predict and subsequently reduce the sound pressure levels generated by these devices, it is necessary to first predict the total vibrational power injected by them into the supporting building structure. Whilst simplified methods are available for the calculation of the total power through all contacts, it would be beneficial to have more detailed knowledge of the dominant contact powers. For sources on low-mobility building elements, the contact powers are determined by the blocked force, along with the real part of the receiver mobility at each contact. This paper describes a novel inverse method to obtain the blocked forces at each contact. The method employs an instrumented reception plate, which is numerically modelled to allow optimum accelerometer positions to be selected, for any source and any location. The underlying theory and measurement procedure are described, and experimental validations are presented.}, language = {en} } @techreport{HoellerQuirtZeitleretal., author = {H{\"o}ller, Christoph and Quirt, David and Zeitler, Berndt and Sabourin, Ivan}, title = {Apparent sound insulation in cold-formed steel-framed buildings}, publisher = {National Research Council of Canada.
