emWave2 Tones and Sounds
Startup Indicators
When you first turn on the emWave2, the number of tones indicates the active mode:
-
Two Tones: The device is in Basic Mode.
-
Three Tones: The device is in Advanced Mode.
Coherence Level Feedback
Audio feedback helps you track your state in real-time. By default, a tone sounds every 5 seconds corresponding to your current coherence level:
-
Medium Coherence (Blue): A standard pitch chime.
-
High Coherence (Green): A higher-pitched, ascending chime.
-
Low Coherence (Red): No tone is played on the handheld unit. Note that Low Coherence simply means your rhythm is not yet optimal; it is not a "negative" indicator.
Reward Tones and Achievement
As you maintain coherence, blue bars accumulate on the Heart Action Strip. When these bars reach the top, you will hear a distinct series of reward tones. The strip then resets to the bottom to begin accumulating bars for your next reward.
Battery Alerts
A fully charged emWave2 typically lasts 5 to 6 hours. When the battery is nearly depleted (approximately 2 minutes of use remaining), the device sounds a soft 3-tone chime. This alert repeats with increasing frequency as the power continues to drop.
Managing Audio Settings
On the Handheld Device: To change the volume or mute the device, start a session and wait for the breath pacer lights to begin moving. Press the bottom portion of the sensor button to cycle through four volume levels.
In the emWave Software: When using the emWave2 with the desktop software (Pro or emWave2), you can customize the audio further:
-
Go to Preferences and select the Sounds tab.
-
Adjust the Volume slider or Enable/Disable specific tones.
-
Choose the Chime Frequency: You can set tones to play every 5 seconds or only when your coherence level changes.
-
Use the Sound icon in the lower-right corner of the Session view for quick muting during a live session.
