Sound level meter comparison
This is an alphabetically ordered table of various sound level meters, i.e. test and measurement equipment which measures the sound pressure level and can log data your PC via USB, RS232, and so on. We do not list devices without PC logging functionality, as those are not really useful for sigrok.
This page lists commercial and non-commercial devices with a short overview of their capabilities. We list all kinds of devices here, not only those supported by sigrok.
You should not use the information here as the sole source for any buying decisions, this is just meant for informational purposes. Please carefully check the vendor websites if you intend to buy any hardware.

1 It is unclear if the meter can stream data live, or only log to SD card. Does not appear to be compliant to IEC 61672-1:2003: time-weighted measurements are wrong, and frequency-weighting C is also wrong.
2 More likely made by Tecpel.
3 This is a rebadged CEM DT-173.
