Electronic automotive diagnostic stethoscope DS-3 is used to listen to acoustic effects of working parts of vehicles and machines. It is equipped with signal level indicator, allowing to quickly estimate the amplitude of vibrations in a 10 point scale. Fully digital signal processing allows for clean and undistorted sound in the headphones. Stethoscope offers selectable digital filter cutting out frequencies above one of 10 pre-defined values that can improve hearing sounds overpowered by high-frequency noise and vibrations.
