1、Summary

  JH1-HS5670 impulse integral sound meter increases key circuits of integral operation,clock enactment,CUP microprocessor,multifunctional LCD on the base
of general sound meter,can quickly and precisely measure data of equivalent continuous sound LEQ,single blast sound LAE,sound pressure LP,testing time TIME,and then the ammeter and LCD show instant measure result synchronously,
so it is a portable precise acoustic measure apparatus,which can measure and analyse noise of surrounding,machine,vehicle,electrical machinery,architecture acoustics and electroacoustics,its trait of impulse and peak value keep can exactly measure peak value of concussion sound ,impulse sound and noise .
