13. 61 Calibrate Calibration screen Calibrate Quest Technologies recommends calibrating your Verifier before you run a STI PA measurement and after to ensure highly accurate measurement results The microphone should be calibrated before use for a number of reasons First the microphone is sensitive to humidity and pressure changes Calibrating before taking measurements assures that your level measurements are accurate for the current environment Performing a calibration verification post cal allows you to verify that conditions have not significantly affected your readings Calibrating also serves the dual purpose of checking the microphone for significant damage such as a torn or contaminated diaphragm You can calibrate the instrument in the field with reference to the output of a calibrated sound source Quest offers a line of acoustic calibrators that are available such as the QC10 20 Calibration screen The Calibration screen contains a calibration option called Calibrate and a Calibration History The history shows Pre Calibration Pre Cal and Post Calibration Post Cal results for previous calibrations as applicable For each calibration type the resulting SPL level is shown along with the time and the date of the calibration Pre Calibration The main reason to calibrate is to adjust the current microphone reading to match a reference input usually provided by a calibrator A Pre Calibration is conducted wh

23. Reverberation e STI PA e Curves Reverberation Reverberation is the distribution of sound in an enclosed space after the sound is removed or decayed How is reverberation or reverb created in enclosed spaces A sound is generated in an enclosed structure with a combination of the direct sound source which travels from the sound source to listener by the shortest path without interfering with room surfaces and the reflected indirect sound source The total sound source echoes and decays as the sound is absorbed by the materials in the room i e walls carpet furniture concrete etc and air This is noticeable when the sound source stops but the reflections continue decreasing in amplitude until they can no longer be heard SoundPre Models SE and DL 78 Additional options Reverberation time RT60 Reverberation time RT60 Reverberation time is a measurement used to evaluate and measure sound decay in a specific space tailored to speech or music such as classrooms auditoriums gymnasiums concert halls theatres etc For room acoustic results are used to ensure quality sound is evenly dispersed throughout a specific room with limited echoes refractions For music or performance auditoriums i e symphonies higher reverb time is preferred so the ending results are more robust The Reverberation Time over each octave band can be analyzed using a decay curve Each octave band shows the time of sound at the start and a

Interrupted method uses a constant sound source i e dodecahedral speaker waiting for the level to stabilize and then the source is turned off The method uses random noise or pink noise to test reverb time Impulse mpulse method is when the user tests the room with a broad spectrum impulsive noise such as a starter pistol or a balloon popping Measurement The RT60 result times for each filter band of the 1 1 Octave or 1 3 Octave modes are averaged across the studies to arrive at a session average RT60 for that frequency band Ensemble The decay curves for each filter band of the 1 1 Octave or 1 3 Octave modes are averaged across the studies to arrive at an average session decay curve for that frequency band that is then used to calculate the session RT60 for that band This results in either eight or twenty four session ensembles one for each frequency band in 1 1 Octave or 1 3 Octave modes respectively Auto This is the default threshold setting The instrument will automatically chose the level and calculate RT60 When in run mode it sets the threshold relative to the noise level in the room It provides a trigger level which is customized to each band 40 dB 140 dB in 1dB increments The threshold decibel is user selectable between 40 dB to 140 dB in one decibel increments e For Interrupted Noise method level below this threshold will trigger the start of a measurement e For Impulse method levels
