Plaintiff's Exhibit 6


Select the desired Response and Weighting. If the sound source consists of short bursts, or if you're interested in peak values only, set R ESPONSE to FAST. To measure average sound levels, use the SLOW setting. Select A-weighting for noise-level determinations, and C-weighting for measuring sound levels of musical material.

Determine the appropriate Range setting.

Start with the highest setting (120 dB) and work downward until there is significant deflection of the needle. For greatest accuracy, always use the lower of any two possible settings. Example: If RANGE is set to 80 dB and meter reads around—5, reset RANGE to 70 dB and meter will read + 3, for an actual sound level of 73 dB.

Important Note: For meaningful readings, any particular sound to be measured should be at least 10 dB louder than the background noise level.

Minimize the effect of your body's presence.
When the sound is coming mainly from one direction, the level reading may be significantly affected by reflections from your body. Do not hold the Meter directly between you and the sound source, as this may produce an error of several decibels in the frequency range above 100 Hz. Position the Meter so that an imaginary line between you and the Meter is perpendicular to a line between the Meter and the sound source. For the most accurate readings, point the microphone towards the sound source when possible.

Handle the Meter carefully.

The microphone and meter movement are fragile and may be damaged if the instrument is dropped. Don't operate the Meter at a range setting that causes "pegging" of the neddle This could damage the movement.
