Sound Reinforcement, Calibration & Analysis

The Right Tools For The Job – Time Energy Frequency (TEF)

Whether for sound reinforcement, calibration, or analysis of an acoustical space, the highly-trained staff at RDI maintains the experience to utilize the most state-of-the-art tools available to achieve maximum performance. The main tool for these circumstances is the application of a computer-based testing system called TEF 25 (Time Energy Frequency Analysis). These tests are performed in a space to create a pre-inspection analysis, which determines the actual acoustical properties of any given room.

Utilizing TEF to test the quality of existing sound systems and acoustics, our staff can make the following measurements:

  • Energy Time Curve (ETC)
  • Time Display Spectrometry (TDS)
  • Real-Time Analysis (RTA)
  • ALCONS Measurements
  • Rapid Speech Transmission Index (RASTI)
  • RT 60 Measurements
  • Noise Criteria
TEF Analysis

System Measurement Acoustic Analysis Real-time Tool (SMAART)

For post-analysis of an enclosed space or a sound system, our experts also utilize another measurement system called SMAART.

System MeasurementSystem Measurement – This is an analyzer. Our engineers examine individual channels and take those signals apart to examine their level, frequency content, duration, etc. We then can compare both signals, identifying “what went in” to a system to the “what came out,” to determine what happened in between. In other words, what our systems (electronics, speakers, and acoustical environments) are doing to the signals passing through them (frequency response, impulse response).

 

Acoustic AnalysisAcoustic Analysis – By doing system measurements, our engineers can use those measurements to help map out sound system configurations for your setting and how we best set up the setting to receive the sound system within the acoustical space.

 

Real-Time ToolReal-time Tool – This extremely powerful analyzer was built to be used, as a calibration and measurement tool for setting and tuning the sound reinforcement system.

 

A Winning Combination

Both TEF 25 and SMAART are tools used in conjunction with other test instruments to assist in both sound reinforcement calibration and analyzing the acoustical properties of rooms. These instruments include oscilloscopes, frequency generators, frequency counters, and a variety of calibrated measurement microphones. As engineers, these tools help us identify tones or frequencies of interest as well as feedback suppression, channel equalization, and aligning the sound system speakers for peak performance. These tools give our technical staff the proper tools to ensure the success of our projects.
