::Sem A: Acoustics::
Acoustics for Live Sound Engineers
The objective of this seminar is to learn some practical acoustic theory that will help you to justify good habits, destroy bad ones and develop a better approach to choosing and using speaker systems. We will discuss why the speaker system is the most important part of any sound reinforcement solution. This will be a hard hitting and technical session but you will also spend moments running around with your eyes closed holding an SPL meter.
The Days Course will cover topics including:
- Understanding Loudness: The dB SPL scale
- Relating system power to dB SPL
- Speaker space relationships
- Quantitative and qualitative listening
- Understanding acoustic wavelength and frequency ranges
- Mapping level drop over distance
- Defining intelligibility
- Speaker System Design Fundamentals
- Target for speaker system sizing
- Mapping control of dispersion
- Understanding Comb Filtering
- Understanding Driver Interaction
- How does horn size effect dispersion?
- What is a "Long Throw System"?
- Narrow dispersion systems
- Quantifying level drop over distance
- System arrays and box interaction
- What is a line array?
