Casella CEL-630.B1/K2 Type 1 Octave Sound Meter Kit with Software

Description

Most sound meters incorporate a processing network that assigns relative importance to low-, middle-, and high-frequency signals. By comparing differently weighted measurements, you can isolate the source of problem sounds. "A" Weighting attenuates the lower frequencies to approximate the response of the human ear, which is most sensitive to frequencies between 3000 and 4000 Hz. "B" Weighting gives decibel readings of combined high- and middle-frequency signals. Use in conjunction with A weighting to isolate sounds that are causing a problem. "C" Weighting reads all frequencies the same but gives a better response to higher frequencies than A or B weighting. Use to pinpoint problems when A or B weighted scale readings are very high. Applications Basic noise surveys Machinery measurements for product noise reduction Selection of hearing protection Basic noise control measurements Workplace noise surveys for compliance measurements Noise mapping applications General purpose noise measurements These sound meters are designed to help you interpret changing noise climates and measure them correctly. Meters feature a unique DSP technology allowing the simultaneous capture of sound parameters with A, C, and Z frequency weightings, slow, fast, and impulse time responses, over a full 120 dB dynamic range. All noise parameters are measured and stored such as current sound level, maximum, minimum, time average, peak and TWA (with optional threshold). The menu driven interface makes these meters easy set up and use. USB interface allows measurement data to be easily transferred to spreadsheets or other office documents, and models with Insight software allow you to further analyze data and easily generate reports. The CEL-630 models include all of the features of the CEL-620 series and provide additional extensive data logging time history recording that is particularly useful for environmental noise recording at regular intervals. Regular samples can also
