Nice overview of some areas that I wondered about with regard to multifamily structures

Architectural Designer, AECOM

Excellent course and material.

This is a group of four recorded presentations made at panel at the ASHRAE 2016 Winter Conference in Orlando Florida. The topics include intermediate and advanced course material on four related but distinct topics in acoustics. They could each reasonably stand alone in this distance learning environment.

The presentations on plumbing and sound isolation are quite accessible. The presentations on sound control of MVHR systems and outdoor equipment sound rating calculations are for experts. The presenter for the Sound Isolation between Multi-Family Units would be well-served by creating a slide deck with slides that work - while the information is good, having to say that we'll skip through slides quickly because they don't work to illustrate his points isn't appropriate.

Each of the presenters has quite a bit of technical expertise in their respective fields. Their presentations are more technical in spirit and detail than many general LEED practitioners will be accustomed to. They are appropriate for mid to senior level design, engineering and field construction/inspection professionals who have some responsibility for delivering acoustic quality in multi-family projects. Others may find the presentations granular. For example, learning the ins and outs of ANSI/AHRI methods for estimating the A-weighted sound pressure level at a person, property line, or window is a narrow and deep exploration.

The general point of each of the presentations is that acoustic considerations are best addressed in design phase and solutions must be as carefully shepherded through construction as other critical environmental quality considerations. Each presentation carefully guides the viewer from problem identification through tools for analysis with reasonable explanations of appropriate practice applications. Solid courses.

Very well done course on Acoustics in Multi-Family Residential Environments.

The course is slightly more advanced than some of the other courses here but well worth your time

What I found interesting on the discussion on Acoustics is:

- Where to place hardware such as kitchen appliances related to other rooms.
- Noise related to plumbing. How they recommend keep plumbing from the walls of a bedroom.

The quality of the video was very good and it flowed well.

I did struggle a little on presentation 3: Using and Understanding AHRI 275: Application of Outdoor Equipment Sound Ratings only because it was equation heavy.

This is not a bad thing, but just keep this in mind when taking this course.

Well worth your time!


Good content. Delivery was broken up to much.

Excellent course since it covers several noise factors in multi family residences

This is a highly technical course. I would consider this to be 'advanced' when compared to other intermediate LEED CE courses. With this being said, this is an important topic that should not be overlooked for those connected to the multi-family industry.

Mechanical Engineer, DAR

it was awsome

This course provides a valuable information about sound isolation challenges in multifamily residential and hotel projects and the methods of achieving a suitable acoustic environment. The course consists of 4 modules discussing Plumbing Noise Control Essentials, Sound Isolation Methods, Understanding AHRI 275: Application of Outdoor Equipment Sound Ratings, and Ensuring Mechanical Ventilation with Heat Recovery (MVHR) Systems Are Quiet.
The course is essentially recommended for Architects, Mechanical Engineers, Commissioning Engineers and CxA. For LEED Project Administrators, the subject of interest would be and explanation of STC – Sound Transmission Class metrics which is used in the LEED v4 EQ credit: “Acoustic Performance and Sound Isolation.
The course quality may be improved by providing a correct reference to the LEED v4 Reference Guide, as given above and eliminating some typo mistakes, like indicating a wrong number for allowable Sound Pressure Level in the bathroom and kitchen: the course gives 45 dBA when in fact it is 40 dBA as per the 2015 AHRAE Handbook, HVAC Applications, Chapter 48, Table 1.
However, these comments do not reduce the value of this course. This course is recommended to everybody who needs better understanding of the noise control requirements in buildings.
