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.

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

Understanding Air-Conditioning and Heat Pump Ratings

HVAC units are rated and certified to defined metrics and in many cases, must meet government regulated minimal standards before they can be offered for sales. Designers of systems using his equipment need to understand what these ratings mean in order to apply the best type unit in the system for a given application. This presentation will cover:

• Different rating metrics for full load and part load performance
• What environmental conditions are these units tested at to develop the ratings
• What the rating cover and don’t cover
• How these rating effect the energy consumption of systems and overall building performance
What’s Loud - 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

What’s Shakin’ – 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

Failure is the Option - How failure, perseverance, and positive attitude lead to innovation and success

To invent, innovate and discover new concepts, processes or products we must push the boundaries of our knowledge and experience past where we are today. You cannot discover how far you can go without exceeding the limits and failing so that we know what the limits are. This presentation draws on the wisdom and experience of some the most innovative and successful figures currently and in history for wisdom on how to fail and win. This presentation will cover:

• Realize how failure leads to successful outcomes
• Know the difference between an acceptable and unacceptable failure
• Discover how to "make your own luck" through perseverance
• Understand how learning from others mistakes can make us more successful and allow us to learn from our own
