            DISCLAIMER


            This Report by Alpha Acoustics Pty Ltd is prepared for a particular Client and is based on the agreed objective, scope, conditions and
            limitations as may be stated in the Executive summary. The Report presents only the information that Alpha Acoustics Pty Ltd believes,
            in its professional opinion, is relevant and necessary to describe the issues involved. The Report should not be 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 Pty Ltd. The Client is authorised, upon payment to Alpha Acoustics Pty Ltd of the agreed Report
            preparation fee, to provide this Report in full to any third party.

            Recommendations made in this report are intended to resolve acoustical problems only. We make no claim of expertise in other areas
            and draw your attention to the possibility that our recommendations may not meet the structural, fire, thermal, or other aspects of
            building construction

            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 Rw 50 to Rw 40. Therefore the use of contractors that are
            experienced in acoustic construction is encouraged. Furthermore, two insulation products may have the same thermal R rating but the
            sound absorption of one may be entirely deficient, therefore the use of materials and equipment that are supported by acoustic laboratory
            test data is encouraged.
