The 2010 release was the first to include a subsection entitled Sound and Vibration: Design Guidelines for Health Care Settings. They not only serve as a guide for regulatory codes, but also outline best practices for those involved in the design of healthcare facilities. Floors above fully enclosed garages and carports, if constructed as defined below, are considered minimum requirements. When building condominiums and apartments, you must obtain a CTS 50 for defogging units and hallway walls in accordance with the International Building Code. Most other assignments have no code requirements, but there is an economically reasonable expectation of voice privacy between neighboring units. Exception: Doors that meet the following criteria are considered to meet STC-26: P100 requires all new construction and major renovations to achieve a LEED v4 Gold rating that meets the appropriate usage requirements. The standards provide four levels of performance within which buildings can be categorized. Below are the requirements for outdoor wall mounting, which is primarily designed for general office use and can be customized for other applications or applications. Any discussion of sustainable building practices almost always includes LEED v4.
It is the most recognized and widely used building rating system in the world. In Canada, LEED v4 is administered by the Canada Green Building Council (CGCC); in the United States, by the US Green Building Council. The two parts of LEED that apply to schools and health facilities mentioned above have been incorporated into LEED v4. These requirements are often met when carpet is used as flooring. However, hard-hit floors cause real problems with sound transmission. In particular, the trend towards stone and tile floors means that apartment planners can no longer rely on carpets to solve the problem. Designers need to pay more attention to the design of floor-to-ceiling assemblies to meet certain standards. Airports and urban interfaces are other areas in which acoustics are examined. For Air Installation Compatibility Use Zones (AICUZ), the U.S. Department of Defense describes recommended noise level reductions based on the surrounding average day-night noise level.
These government standards are not strict baseline requirements, but as the map below shows, AICUZ zones have noise limits that are measured and adhered to when these aircraft take off and land. Section 1206 requires that common interior walls, partitions and floor/ceiling assemblies designed and/or constructed between adjacent living and sleeping units and between these units and common areas (including, but not limited to, corridors, corridors, stairs or service areas) must have a minimum level of sound separation. It should be noted that these rules of Article 1206 apply only to dwelling units and sleeping units and are therefore primarily residential in nature. Therefore, sound separation should be considered when planning or constructing such separations. The code requires two types of sound insulation: airborne noise control and structural noise control. The criteria in these sections specify minimum requirements for the acoustic design of the exterior envelope of buildings as well as for HVAC systems and their parts. These requirements apply to all human buildings located in SeaTac Noise program areas. The indoor noise level standard for the living areas of eligible structures is an average day-night sound level of 45 decibels or less. (Ord. 16-1008 § 9 (part): Ord.
04-1008 § 3) The main standard that addresses this issue is ANSI/ASA S12.60, which provides information on acoustic performance criteria, design requirements and guidelines for schools. There are two interesting parts, Part 1: Continuing Schools and Part 2: Movable Class Factors (applicable to portable devices). (1) Doors other than those described in this section shall have a laboratory sound transmission class of at least STC-26. b. Ceiling insulation must not be less than R-38 or lower than the minimum requirements of the SeaTac Energy Code. Insulation must be installed with an average airspace of at least six (6) inches between the insulation and the roof deck. B. The exterior envelope of the building must be sealed in accordance with the air leakage requirements of the SeaTac Energy Code for residential or non-residential buildings. Other penetrations through the wall, floor or roof/ceiling not specifically referred to in these sections shall be designed to limit sound transmission and shall have the same average laboratory sound transmission classification as for doors.
