Addressing Sound Transmission in Residence (HSW)

Ever since the beginning of multi-family dwellings, sound isolation between residential units has generated significant tension. Residents want privacy from the people living next to them, even though they may be less than a few feet away from one another. According to the International Building Code, partitions and constructions between residences should have a minimum Sound Transmission Class (STC) of 50 and a minimum Impact Insulation Class (IIC) of 50 (45 if field measured). This language has been adopted by many state building codes including New Hampshire and Massachusetts.

How to be a Good Neighbor: What You Need to Know about Emergency Generator Noise (HSW)

Emergency generators are a component of a wide range of buildings from private residences to public hospitals. Regardless of the emergency generator’s size, noise emission is a common community concern. We will examine noise regulations concerning emergency generators and share noise mitigation solutions to be a good neighbor.

Help! There is a Sound Problem! (HSW)

Recent trends show developers and end-users modifying existing spaces to serve a shifting array of needs; often these decisions are driven by cost. Spaces suited for one purpose could be acoustically unsuitable for another. Achieving a suitably acceptable compromise can be very challenging in an existing building where structural limitations or other feasibility issues are apparent. This program reviews a number of case studies and will teach you how to calibrate, anticipate, and address expectations or potential issues to avert an ‘acoustical disaster’.

Auralizations: A Useful Tool in the Decision-Making Process (HSW)

Learn how an auralization, or 3DListening®, illustrates the sound quality of a room and demonstrates the acoustical difference among treatment options. See and hear examples where auralizations helped the client decide which treatments were appropriate for their budget and needs. Case studies will include the Museum of Fine Arts, a renovated natatorium at Brandeis University, and the Xielo Restaurant.

Where Musicians Hone Their Craft: Acoustical Designs of Practice and Rehearsal Rooms (HSW)

For every performance, musicians spend countless hours in rehearsal and individual practice. Because these rooms are teaching and learning spaces, they play as important a role in the musical discipline as the performance hall. Practice and rehearsal room acoustical design must provide clarity and intelligibility, comfort, hearing safety, and freedom from intrusive sounds. Learn about key design factors including room size and dimensions, arrangement of surface finishes, low background noise, and sound isolation to and from neighboring spaces.

Controlling the Acoustics of Large Atriums (HSW)

This presentation will start by explaining how the programmed uses of an atrium space affect decisions about the acoustical design. For atriums where speech intelligibility is important, the design variables of interior volume (in cubic feet), selection of sound absorbing finish materials, and appropriate sound system technology will be discussed. (Note: this auralization is available by attending this seminar in Acentech’s Cambridge Office. There may be special circumstances that can allow this auralization to be conducted at alternate facilities; however, this needs to be discussed prior to confirming such an event.)

Green Acoustics: Acoustics on Green/Sustainable Projects (HSW)

Green/sustainable practices are revolutionizing the design and construction industry, providing many benefits to the owners, occupants and the environment through smarter use of energy, water and material resources and improved indoor environmental conditions. In many ways, acoustics and sustainable design complement each other toward achieving higher quality results for projects; however, there are also ways that the two topics can significantly conflict. This presentation will discuss the potential synergies and conflicts within these two design objectives.

Sounds Great! Design Considerations for Tough Spaces (HSW)

Innovative spaces that serve multiple purposes are most successful when they are aesthetically pleasing and achieve the intended acoustic goals. Forward-thinking ideas and technologies can create designs that “sound great”— both literally and figuratively. Spaces used by multiple departments in the corporate or academic worlds often serve several groups with different needs, ranging from group discussions to speaker presentations to several one-on-one conversations. Newly constructed and renovated spaces present unique challenges in catering to the varying preferences. Properly designed spaces that can be modified easily and quickly according to the users’ requirements can result in considerable savings in cost and square footage.

Green Design: Innovations and hidden opportunities (HSW)

This session presents an overview of various ways in which sustainable design can be applied to acoustics, audiovisual systems and information technology to extend Green Design concepts. For most architects, a LEED-centric building is the big picture objective, but extending ‘green techniques’ to ancillary components of the design can have a positive long-term impact and cost-savings for clients. Eco-friendly materials and automated power reduction techniques can be used to create spaces that are not only environmentally conscious but also highly functional.

Variable Acoustics in Performance Spaces

This session will explore ways designers can incorporate a wide range of systems and materials to accommodate a variety of acoustics program requirements. Learn about time patterns, spatial relationships, and successful models.
