ACOUSTICS Sample Clauses
POPULAR SAMPLE Copied 1 times
ACOUSTICS. Given the proximity to the site to the CN Rail lines and the Evergreen Line guideway, the applicants have provided a report from an acoustic consultant summarizing the potential for ground vibration and airborne noise. The report includes recommendation the building design and materials to manage the noise from the rail uses in accordance with applicable standards. The report is included as Attachment 8. If the project proceeds, the report will be registered on title by covenant to ensure that the recommendations are addressed in a building permit submission. A copy of the latest scored Sustainability Report Card is included as Attachment 9. Overall, for all pillars, the project scores 42%. There may be other opportunities to increase the scoring which will be identified through the final review of the project plans.
ACOUSTICS. AV System All information in this document will be considered as in support of the AV system. There may be additional infrastructure requirements unrelated to the AV system, and thus not contained herein, but that are still necessary for the space to be fit for intended use.
ACOUSTICS. Acoustical requirements are subject to an acoustical report generated by a qualified acoustical engineer. This report will address acoustical requirements for the HVAC system, ambient noise levels, lighting ballasts, reflective surfaces, treatments, reverberation, and other noise mitigation methodologies.
1. Room acoustics play a key role in ensuring presenter and audience speech intelligibility.
2. Refer to Appendix 3D Sound Transmission Ratings. FINAL DRAFT
3. There are three key parameters:
a. Background noise which considers ambient noise from HVAC and other systems that may create continuous/intermittent noise in the space,
b. Sound isolation which considers noise transfer from outside the space to inside the space; and
c. Interior acoustics which consider the movement and reflection of sound waves within the room.

The sound power level is measured in dB relative to 10-12 ▇▇▇▇▇, at the exhaust plenum exit, under base load conditions. Measuring procedures are in accordance with ASME PTC 36 (near field) and/or ANSI B133.8 (far field).
ACOUSTICS. Performance tests shall include testing for maximum background noise as defined by the OSDM. Tests are to be taken in twenty percent (20%) of estimated worst-case instructional spaces;

ACOUSTICS. Our scope include acoustic recommendations for partition types, door types, ceiling reflectors, HVAC noise control and acoustical treatments. Acoustical sound modeling will be provided in critical spaces to ensure the design meets established criteria as attainable within the Owner’s budget. Available Additional Services will include the following and are not reflected in the current proposed fees:
1. Traffic Engineering: (If required or requested). Includes data collection. A site visit will be completed to identify and record the existing roadway conditions. This includes the subject property, the existing number of roadway lanes, roadway width, signage, traffic control, bike routes, pedestrian paths, public transportation, and adjacent land uses. Intersection traffic counts will be conducted between the hours of 7:00 AM and 9:00 AM, and 4:00 PM and 6:00 PM on a weekday, and from 11:00 AM to 1:00 PM at the intersections surrounding Cumberland Park.
ACOUSTICS. Develop acoustical requirements in conformance with State and other applicable regulations for all spaces within the Project. Provide recommendations on criteria to the Public Infrastructure Department and strategies for ensuring that criteria have been achieved. Provide plan for integrating acoustical requirements into the final bid documents and for overall quality control plan to ensure that acoustical criteria are achieved.

ACOUSTICS a. Design and construct the lecture room with appropriate acoustical conditions to make the room functional for large meetings, multimedia AV presentations, and video conferencing.
b. Ambient noise including HVAC and electrical or mechanical noise will be controlled, and appropriate acoustical treatment will be installed to control reverberation, minimize reflections, flutter echo and other acoustical issues that may adversely affect the microphones pickup.
c. Hard reflective wall or ceiling surfaces within 2500mm of lectern or table top microphones will be avoided, and may require the addition of absorption or diffusion materials as the reflections from these surfaces will create audible artefacts or lower feedback thresholds.
d. Carpet is always preferred in large conference rooms as it absorbs unwanted sounds well. If the lecture room can not have carpet the flooring material is to be a cushioned vinyl of a type with highest absorption coefficient and least acoustical reflection properties
e. Project Co. is to provide stackable chairs with padded seats and padded backs to absorb sound and minimize acoustic reflections. Confirm colour and finish with the Authority for approval prior to procurement. Chair bases must not be of a type that will damage mic or power cables that connect to the floorboxes
f. Provide fabric covered medium density fibreglass panels at 1000 mm AFF and extending to 2500 mm AFF on the two sidewalls and rear wall. The panel construction will be:
1. Minimum 50 mm thick pre-finished acoustic panels on the rear wall. Minimum Noise Reduction Coefficient (NRC) 0.95 rating.
2. Minimum 25 mm thick pre-finished acoustic panels on the side walls. Minimum NRC 0.85 rating.
3. Contiguous application over certain areas as may be required to meet the requirements of this Appendix.
g. An acoustic ceiling is required. It will have a minimum NRC rating of 0.70 and a minimum Ceiling Attenuation Class (CAC) rating of 35. In addition, the ceiling will be back loaded with batt insulation (bagged, if necessary) to broaden the sound absorbing range.
h. Concave curved wall and ceiling surfaces focus sound and are to be avoided. Any concave curved surface must be treated with suitable broadband acoustic treatment to absorb or diffuse the sound wave front.
i. The 100% occupied reverberation time will not exceed 0.6 seconds (mid-band), and the 70% occupied reverberation time will not exceed 0.7 seconds (mid-band), in the room.
j. Background Noise
