Michael Curtis leads the discussion of acoustic measurement using source independent FFT tools. Office Hours for 5/24/2023 - Show # 1156 00:00 Start 5:09 First hour questions in comments 01:05:18 ** Acoustic Measurements ** 01:38:44 What is the best method for measuring speech intelligibility in conference room or presentation space? Thanks! 01:40:59 What methods can be used to locate a microphone in a small isolation booth to minimize room mode pressure zone pickup? Typical dimensions: 1x1.5x2.2m 01:42:43 What is the best way to use glass in a conference space with the least amount of sound reflections? Thanks! 01:48:02 Is there any value at all doing traditional acoustic measurements in a typical pre-fab voiceover booth, or do the small dimensions break the math models? 01:49:41 Why have a system target that is not flat? That would mean that the same mix on a different system may sound thin or boomy. Why not make the mix sound as intended from the get go? 01:51:43 Can you please recommend some lower cost audio quality measurement tools? Thanks! 01:52:45 How important is it to optimize signal to noise in the measurement - from increasing the level of the reference signal in the room to using quiet and accurate preamps and audio interfaces? Dolby says no to Scarletts for measurement for example. 01:54:58 When the sound quality of a given space is different at different locations, what are a few methods to solve this type of problem? 01:58:42 Would like to hear your philosophy on the importance of phase before and after measuring and utilizing transfer functions. 02:00:59 What are a couple of common mistakes when setting up a basic audio system for a live audience? 02:03:26 When tuning a room, How do you adjust for an empty room vs a room full of people? How do those measurements typically differ? 02:04:46 We’re using SMAART with a DBX Mic for our Nexo rig in the usual left/right stack placement. How should I utilize the messurement setup during the live gig, and what to look for to improve the result. #aucoustics #audio #measurement *When Does Office Hours Happen* We meet every day!
