When: Wednesday 3/22. 2-4 pm ET
This webinar will introduce you to the basic principles and terminology of acoustics, and noise control engineering in buildings. You will learn about sound pressure levels, sound power levels, sound intensity levels, vibration levels, frequency, temporal variations, loudness, vibration transmissibility and vibration isolation. You will learn about Noise Criteria (NC) and Room Criteria (RC) curves and how they are used in acoustical engineering projects. Speech Interference Levels (SIL), Sound Pressure Levels (SPL) and Room Constants are also introduced, and you will see how the principles of sound Transmission Loss (TL), Noise Reduction (NR) and Sound Transmission Class (STC) are used in project design. The information you will get from this webinar will allow you to apply basic acoustical engineering principles to a variety of projects, and will give you the background you need to advance to more sophisticated analyses on more demanding acoustical challenges such as those associated with design of concert halls and recording studios.

Learning Objectives
At the successful conclusion of this webinar, you’ll be able to identify and discuss:- Learn the definition of a decibel and how it is calculated
- Learn how to add, subtract and average decibel levels
- Learn the definition of and how to calculate sound pressure level
- Learn the definition of and how to calculate sound power level
- Learn the definition of and how to calculate sound intensity level
- Learn the definition of A-, B- and C-weighted sound levels and how they are applied
- Learn how noise associated with buildings is defined in terms of Noise Criteria and Room Criteria
- Learn about designing to mitigate speech interference in the acoustic environment
- Learn how sound pressure level (SPL) varies with distance and absorption
- Learn basic principles underlying estimation and use of Room Constants
- Learn how the principles of sound Transmission Loss (TL), Noise Reduction (NR) and Sound Transmissi
poor use of the time – too much on reading the slides and not enough on use.
The presenter offered no insights. The definitions and table are available in any textbook. The presenter needed to introduce the concepts of noise control and how they relate to buildings – this was not done
Poor internet connection on presenter’s part caused disruptions and missed information.
While I appreciated the technical nature of the course, it would be more enlightening and enlivening if there are application slides showing pictures/drawings/real world applications to what the instructor is describing when he reaches those sections of the course or to use as examples – illustrations can expand on a verbal discourse and keep the listener even more engaged. Given the wealth of experience the instructor has, some of his real world work would be interesting to see for applying theory/science/formulas into practice/solurions.
The presentation was easy to understand and very informative.
