Questâ€™s new SoundPro DLX hand-held acoustic measurement system is a PDA-style device that performs tests up to 97 percent faster than traditional octave band analyzers with improved accuracy. The real-time frequency analyzer can also act as an acoustical data Web server. The unit captures voice notes and drawings in the field and stores them electronically.Quest Technologies, Inc., Oconomowoc, WI.
