RADIO SHACK用法
團購了個SOUND METER, 睇左INSTRCUTION都唔係太明舍邊個方法同SETTING係for d咩野.........如果for av setting,用weighting a or c?
response time又點決定?
continuous average measurement同integrated average measurements又點決定用邊隻?
max and min又是..佢話用係undertermined既time period....點為止undertermined?
因為新手玩sound meter, 所以好呢hea..
謝謝ching

response time < slow
