**Step 8: Adjust Sensitivity (If Needed)**

If your Google Home device is triggering false positives (detecting sounds when they aren’t actually present), you may need to adjust the sensitivity settings. If the sensitivity is too high, it will be more likely to trigger false positives. If the sensitivity is too low, it may not detect the sounds you want it to detect.

To adjust the sensitivity, go back to the sound detection settings in the Google Home app and look for a sensitivity slider or similar control. Experiment with different sensitivity levels until you find a setting that works well for your environment.

**Step 9: Enable Audio Recording (Optional)**

Some Google Home devices offer the option to record audio snippets when a sound is detected. This can be helpful for verifying the alert and understanding the context. However, it’s essential to consider the privacy implications before enabling this feature.

To enable audio recording, look for an option such as “Record audio snippets” or “Save recordings of events” in the sound detection settings. If you choose to enable this feature, be aware that the recordings will be stored by Google and may be subject to Google’s privacy policy.

*Important Privacy Note:* Carefully consider the privacy implications of audio recording. Understand how Google stores and uses the recordings. Be transparent with other members of your household about the fact that audio is being recorded.

**Step 10: Create Routines Based on Sound Detection (Optional)**

One of the most powerful features of sound detection is the ability to trigger routines based on the sounds detected. For example, you could create a routine that turns on the lights when glass breaks or sends a text message to a neighbor when your smoke alarm goes off.

Here’s how to create a routine based on sound detection:

1. Open the Google Home app.
2. Tap on “Routines.”
3. Tap on the plus icon (+) to create a new routine.
4. Give your routine a name.
5. Under “When this happens,” select “Sound Detection.” (If you don’t see “Sound Detection”, ensure the feature is enabled as described in the previous steps.)
6. Choose the sound you want to trigger the routine (e.g., “Smoke Alarm”).
7. Under “Then do,” select the actions you want the routine to perform (e.g., “Turn on lights,” “Send a notification”).
8. Save the routine.
