If you're just measuring pink noise or 1000Hz sound or just the noise level of something, this is great. But I quickly found that it wasn't very good as an accurate C-weighted meter. 1) It was not possible to calibrate it. 2) I just had to write down my results for each frequency. Some devices have the ability to display frequency bands. Some can be connected via USB. There is no way out.
