Using ISO Bar Plots to Better Understand Your Loudspeakers
Understand the crucial aspects of designing a sound system with a primary focus on achieving intelligibility - ensuring that sound is clear, high-quality, and understandable in every seat of a venue. Learn from the team at d&b to gain insight on techniques for optimizing sound dispersion and control.
Key Points:
- Intelligibility is designed ad delivering good quality, understandable, and faithful sound to every seat.
- A primary goal in sound system design is to minimize diffuse sound and increase direct sound. This involves adjusting the ratio between the two to enhance clarity and reduce reverberations or echoes.
- Selecting loudspeakers with good pattern control is key to directing sound efficiently and reducing unwanted dispersion.
- The concept of ISO bar plots is introduced as a measure of a loudspeaker’s directivity. These plots help visualize how sound intensity decreases as one moves off-axis and how this behavior changes across different frequencies.
- The overarching goal is to achieve flat, parallel lines in the ISO bar plots across all frequencies. This ensures that sound quality remains consistent regardless of the listener’s position relative to the loudspeaker.
- By achieving better pattern control and reducing the diffuse field, the design aims to increase intelligibility and enhance the overall audio experience for every audience member.
