Q: Do these meters and microphones meet ANSI and ISO specifications for sound level meters? If so, specifically which ones- Type II, Type 1, and so on. What acoustic calibrators can be used with these meters to check calibration before and after surveys?

Provided you’re running both OSX and Windows XP on the system, you can switch to Windows XP and use that for the PAA3 software.  Unfortunately Mac OSX is not supported at this time.

The angle of the microphone will help avoid reflecting sounds reaching the capsule of the mic on the top panel of the PAA2 or PAA3. You may also choose to have it pointing straight, or any other positions, however it will only lock into place at 45 degrees.

As long as the cables are wired correctly you should not have any problems outputting the pink noise.PAA3

Pink noise will provide an even distribution of power across all ISO frequency bands. Being able to visually display what is picked up by a good microphone allows you to determine the frequency characteristics of the room and is a tool to help identify trouble spots that EQ might help you improve. Of course there is no better tool than your ear, so you should use this as the final determining factor for good sound.

With the ever increasing demand for better acoustics, correcting frequency response has become a critical factor in producing a cleaner, more natural sound. The frequency response in rooms and halls has many factors that play into the equation.

Q: I have been trying to store and retrieve saved RTA traces on the PAA2/PAA3. When I enter the main menu, it shows an X beside the Memory selection and will not let me enter the memory section. I can enter the SAVE portion of the memory by pressing the right and enter buttons and it appears that it lets me save the measurement. I can not seem to either retrieve the measurement or more importantly enter the EQ section for the EQ display.

Yes, you can rest assured that Phonic’s PAA2 and PAA3 will work as well for setting up vehicle sound systems as it does for professional sound installations. In fact, many of our customers use our audio analyze to tune up their home theatre or car audio set up. However, you may not be able to use some functions that require the XLR connection, since car stereo systems typically do not use these types of cables.
