8:15 AM – 9:15 AM – Mark Fly – “Acoustics Basics for HVAC&R Designers”
Part of designing a healthy and sustainable built environment for all, involves creating an acoustical environment that is both comfortable and productive. This presentation will expose participants to:
- The fundamentals of acoustics
- How sound is measured and reported
- Levels that are sound spectrums appropriate for different environments and activities
- Different sound measurements and ratings,
- How to apply different types of criteria rating systems to achieve acceptable noise for the people living and working in the space
Participants will get the opportunity to judge for themselves both the loudness and sound quality of different criteria systems available.
9:15 AM – 10:15 AM Dave Bick and Josh Rasch – Acoustical Highlights – Guidelines, Standards, and Codes
10:15 AM – 10:30 AM – Break
10:30 AM – 11:30 AM – Mark Fly – ” Vibration Fundamentals and Human Perception”
Vibration science is discussed with a view toward human comfort in this presentation. Isolation theory including isolation efficiency, damping, and harmonics are explored as well as the distinction between controlling vibration for equipment life vs human comfort. This presentation will cover:
- Understand how vibration isolators work regarding isolation efficiency and damping.
- Learn how deflection and isolator frequency response are related.
- Discover how humans respond to building vibration.
- Look at the criteria used for both human comfort and long machinery life
11:30 AM – 12:30 PM – Lunch
12:30 PM- 1:30 PM – Mark Fly – “Understanding the Psychoacoustics of Hearing and Perception”
This interactive program look in depth into how we hear broadband, time variant and tonal noise. Concepts such as hearing critical band, tonal prominence ratio, and loudness are discussed and presented in audio demonstrations. This presentation will cover:
- Understand What Changes In Levels Are Perceptible
- Learn The Role That Tones Play In Perception And Annoyance
- Understand Critical Bands And How They Effect Perception
- Discover Your Personal Threshold Of Hearing
- Discover Your Frequency Range Of Hearing
1:30 PM- 2:30 PM – Gary Brown and Jared Carrier – “Environmental Acoustics – Acknowledge Code and Avoid Complaints“
2:30 PM– 2:45 PM – Break
2:45PM- 3:45 PM – Mark Fly – “Inside the Box – Fan Characteristics and Applications”
Fans provide the primary transport method for moving thermal energy into occupied spaces in most all cases. Designers need to understand the characteristics and limitations of fans, even if imbedded in into packaged or self-contained equipment to apply the equipment properly. This presentation will cover:
- Different fan types and their characteristics
- Fan curves and fan laws, how to use and apply them
- Fan stall and unstable regions of operation
- How to select the best fan for the flow, static and acoustical performance desired
3:45 PM – Happy Hour

Dave Bick, RCDD, CTS | Electrical + Acoustical + Audio/Visual Designer, McClure Engineering
Since joining McClure in 2003, Mr. Bick has been active in acoustics and audio/visual/security systems from the start of the project to the end. His acoustic projects have included mechanical and environmental noise isolation, room tuning and speech privacy studies. His low voltage projects have included schools, corporate auditoriums, recreation centers, churches, performing arts centers and stadiums. Systems have included steerable array systems, DSP processing, Ethernet distribution/control, digital video recording/distribution, CCTV, door monitoring, card access and digital signage. Mr. Bick has been involved with the commissioning and tuning of hundreds of low voltage systems.
Prior to joining McClure Engineering, Mr. Bick worked for a large, low-voltage communications systems contractor working almost exclusively as a project engineer for the company’s Professional Sound Division. His previous projects include networking the Announcement Control Systems for the two major airports in St. Louis, Missouri, as well as several college and high school theaters, outdoor stadiums, gymnasium systems, hundreds of churches and a renovation to the Gateway International Raceway systems.
Gary Brown | Acoustical, McClure Engineering
Mr. Brown has over 30 years of acoustical and vibration consulting experience. Since joining McClure Engineering in 2012, he has been active in on-site field testing, architectural acoustics, mechanical systems sound isolation, performance space acoustics, vibration analysis, industrial acoustics, and noise control. Prior to joining McClure, he worked at Engineering Dynamics International (EDI), which became EDI Acoustics Inc., when he took over operations in 2010. McClure acquired EDI Acoustics in 2012.
Jared Carrier | Mechanical, McClure Engineering
Since joining McClure in 2018, Mr. Carrier has been active in acoustics and audio/visual systems from the start of the project to the end with an emphasis on noise studies and vibration monitoring.
His work includes noise isolation from mechanical and environmental sources, developing acoustic designs for a variety of spaces including performance halls, libraries and public speaking areas, vibration isolation from mechanical and environmental sources, and heat load analyses.
Josh Rasch | Acoustics + Systems, McClure Engineering
Mr. Rasch’s experience resides in architectural acoustics, noise control, and audio-visual systems design. During his time with McClure Engineering, Mr. Rasch has designed systems for projects that include performing arts center renovations, athletic venues, and universities. His experience in this arena includes signal distribution for a range of systems including access control, intrusion detection, and wireless repeater systems. Additionally, he has experience designing BMS (battery management system) for data center UPS (uninterruptable power supply), large scale lighting control integration, and interfacing with IT system components relying on building network infrastructure.
Within the performing arts sector, his specialties also include video studios, green rooms, podcast spaces and recording studios. His audio-visual systems for these spaces include intelligent conference solutions, large and small facility signal distribution and digital signal processing, steerable array systems, intuitive control designs, interactive video wall hardware design and auditorium design.
