Jade Noise 2
Environmental Noise Monitoring Software

Ptolemy Services produces Jade Noise software for monitoring environmental noise. Jade Noise converts almost any low-cost sound level meter into a data logger using a PC with a standard sound card. Jade Noise will work with a variety of meters from manufacturers such as CEL, Cirrus Research, Bruel and Kjaer, Onno Sokki and others. We have an international perspective and supply the acoustics community world-wide. Jade Noise 2 captures noise data using the AC output from a sound level meter direct to your PC. No special hardware is required - other than a cable! :-)
