You can measure loudness with a simple sound level meter. If you wish to
check your exposure, JansZen can supply a good quality sound level meter
such as we use ourselves at modest cost. Radio Shack also offers one. There
are also apps for smart phones that work as sound level meters and spectrum
analyzers, although they will probably miss the high frequency extremes due
to microphone quality. Follow the instructions for the device or app to make
sure your readings are valid.
