Floor microphone for leak detection: Precisely detect water losses.
What is a floor microphone and why is it essential?
A floor microphone is a highly sensitive acoustic measuring device that is used specifically to locate leaks in drinking water networks. It detects the characteristic sounds of leaking water in the ground - often long before visible damage is visible on the surface. This method is one of the most efficient and reliable methods for identifying leaks at an early stage and repairing them in a targeted manner.
How does leak detection with a ground microphone work?
A water leak under pressure causes typical noise - usually a hissing, whistling or cracking sound. These sound waves spread through the pipe system and the surrounding soil.
The floor microphone captures these sounds with the highestutmost sensitivity, filters out disruptive ambient noise and makes it possible to pinpoint the exact location of the leak. This allows the damaged area to be located efficiently and without unnecessary digging.
Components of a ground microphone:
- Sensor / microphone head - for ground contact
- Amplifier and analysis unit - shows the signal strength visually
- Headphones - for fine acoustic analysis
- Optional: Bluetooth connection & app - for modern workflows
Areas of application for a ground microphone
The ground microphone is always used when possible water damage has already been localized to a specific area - for example with the help of correlatorsmodern sensor technology such as SmartEAR® or cloud-based systems such as POSEYEDON®. Typical areas of application are
- House connections and street sliders
- Asphalted roads and sidewalks
- Urban areas with high network density
- Plastic and metal cables

Advantages of leak detection with a ground microphone
- Fast, pinpoint leak detection
- No excavation necessary
- Saves time and money
- High success rate - even with small leaks
- Ideal in combination with digital early warning systems such as SmartEAR® and POSEYEDON®
What you should look out for when buying
If you want to buy a floor microphone, you should pay particular attention to the sensitivity and the frequency range covered, as these are crucial for detecting even low-level leakage noises. In addition, digital filters play an important role in effectively blocking out disturbing ambient noise such as traffic noise. A robust, weatherproof design is equally important to ensure that the device can withstand the daily demands of outdoor use. Finally, the floor microphone should be easy to transport and convenient to operate to enable efficient and ergonomic use.
Conclusion: Ground microphones are indispensable in drinking water leak detection
Whether with the HL 50-BT for quick deployments or the HL 7000 for complex locating tasks - a modern ground microphone is a key tool for reducing water loss. In combination with digital systems such as POSEYEDON® or the IoT-based early warning system by SmartEAR®leak detection in the drinking water network becomes more efficient than ever.
