Stethophon 04 FEATURES

Minimum Noise Level With Memory Function - Visual assistance to pinpoint water leaks

Current “Minimum” noise level: The noise of a water leak remains fairly constant, however, noise from traffic, wind, and washing machines increase and decrease.
The Stethophon ignores these transient interfering noises and displays only the “quietest” water leak noise (or other source) it has heard during the period you have been listening.

Frequency filtering
Dynamic hearing protection

Last Minimum Noise Level: The previous Minimum Noise Level is stored and displayed; are you closer or further away from the water leak in your present listening location compared to the last?
Is the water leak sound getting louder or quieter?
The higher the value on the display the nearer you are to the water leak.

Frequency filtering

The frequency filter function allows the user to listen to the sound of the water leak at the frequency that best suits their hearing and the frequencies being produced by that particular water leak.
The filters make it easier to hear water leak noises by eliminating many interfering background frequencies.
You can think of it like a graphic equaliser on your music player,choose the frequency band that makes the water leak noise clearest for you.  

Dynamic hearing protection - DHP

The Stethophon 04 water leak detector has a Dynamic Hearing Protection function which mutes the headphones when any loud or sudden noises are detected thus protecting the user's hearing from damage.
