    Actually I found one device with a speaker that reads wav files from sd card and generates the corresponding signal. But I'm looking if there are other devices and other options

    Acoustic signal generator

    Hello everybody, I'm currently testing St mems microphone and I'm trying to measure sound level pressure using a device that emits frequencies between 20Hz and 20Khz ( human hearing range). With that being said Can anyone recommand a device that generates acoustic signal. Thanks in advance.
