   DISCLAIMER

   This Report hy Alpha Acoustics Ply Ltd is prepared for a particular Client and is based on the agreed objcclivc. scope. conditions and
   limitations as may be stated in the Executive summary. The Report presents only the information that Alpha Acoustics Ply Ltd
   believes, in its professional opinion, is relevant and necessary to describe the issues involved. The Report should not he used for
   anything other than the intended purpose and should not be reproduced, presented or reviewed except in full. The intellectual
   property of this Report remains with Alpha Acoustics Ply Ltd. The Client is authorised, upon payment to Alpha Acoustics Ply Ltd of

   Ihe agreed Report preparation fcc, to provide this Report in full to any third party.

   Recommendations made in this report are intended to fC.'mlveacoustical problems only. We make no claim of expertise in other areas
   and draw your attention to the possibility that our recommendations       may nol meet the structural, fire, thennal, or other aspects of

   building construclion

   We encourage clients to check with us before using materials or equipment that are alternative to those specified in our Acoustical

   Report.

   The integrity of acoustic structures is very dependent on installation techniques. For example, a small crack between the top of a wall
   and a ceiling can reduce the effective sound transmission loss of a wall from R", 50 to Rw40. Therefore the use of contractors that are
   experienced in acoustic construction is encouraged. Furthermore, two insulation produCl'i may have the same thermal R rating but the
   sound absorption of one may be entirely deficient, therefore the usc of materials and equipment that arc supported by acoustic

   laboI"'dtorytest data is encouI"'dged.
