What's too loud: Federal OSHA standards say the ear can tolerate eight hours a day of 90-decibel sound (the sound of a well-tuned power mower), four hours at 95 decibels, two hours at 100 decibels, and so on. Many audiologists say those times should be cut in half.
Scantek, Inc. announces the release of a new version of OTL – Terrain™ from Mediterranean Acoustics Research & Development. Before, the software had a sophisticated acoustical calculation engine that simulates 3-dimension sound propagation using sound rays that include divergence, reflection, and diffraction to detect sound paths.
Measuring just 75.5mm x 54.0mm x 37.0mm, the new CEL-120 acoustic calibrator helps users achieve highly accurate calibration of sound level meters in the field.
