Background studies, product facts, and the limits of what we know.
Researchers have studied vibration and grounding using different devices and methods. The studies linked here did not test SoundBlanket and do not establish its effects on sleep or health.
SoundBlanket turns audio into vibration through haptic transducers. Pro adds silver-integrated fabric and a grounding connection. This graphic is an illustration, not a physiological measurement.

Haptic Vibration
SoundBlanket converts audio into vibration through embedded haptic transducers. You choose the audio and adjust the amplifier level.
The amplifier sends the audio signal to the transducers, which produce vibration you can feel through contact with the blanket. Sensation varies with the audio and level.
Low-frequency vibration, HRV, and cognitive performance
✓This trial examined physiological and cognitive responses to a different vibration device. It did not test SoundBlanket, so its results should not be treated as expected SoundBlanket outcomes.
Closed-loop vibration stimulation and sleep
✓This study examined a closed-loop vibration method during sleep. Its equipment and protocol differ from playing audio through SoundBlanket.
Vibroacoustic stimulation and stress measurements
✓Researchers examined psychological, physiological, and cognitive measurements during vibroacoustic stimulation. This is background research, not a SoundBlanket product trial.
Grounding
SoundBlanket Pro has silver integrated into the fabric and includes a grounding cable. Standard does not include this connection.
Silver-integrated fabric provides a conductive path to ground when connected through the included cable. Follow the supplied setup instructions. This product feature does not establish a sleep or health benefit.
Earthing mats and sleep measurements
✓This trial studied an earthing mat and sleep measurements. It did not test SoundBlanket Pro or the combination of grounding and audio-driven vibration.
Grounded sleep and cortisol measurements
✓This small study examined cortisol measurements and self-reported experiences during grounded sleep. It does not establish effects on cortisol, pain, or sleep for SoundBlanket.
Grounding and heart rate variability
✓This publication examines grounding and heart rate variability in a different setup. Its findings do not establish an HRV benefit for SoundBlanket Pro.
Two features. One blanket.
Both blanket models use haptic transducers to turn audio into vibration. Pro also includes silver-integrated fabric and a grounding cable. These are separate product features; research on either one does not establish a combined health benefit for SoundBlanket.
SoundBlanket Pro combines haptic sound with a grounding connection.
Choose Standard for haptic sound with a machine-washable cover, or Pro for silver-integrated grounding fabric. Both include an amplifier.
What we claim. What we don't.
At this price point, you deserve transparency — not marketing dressed up as science. Here's exactly where we stand.
Research in context
The references below cover vibration, grounding, and related topics. Study designs, devices, participants, and publication types differ. Read the original sources to understand each study's methods and limitations.
Honest about what we know
The studies cited here did not test SoundBlanket or its exact combination of features. They do not establish that SoundBlanket changes sleep, HRV, cortisol, or other health outcomes.
Product facts you can compare
SoundBlanket's transducers turn audio into vibration. Both blankets include an amplifier; Pro adds silver-integrated grounding fabric and its connection. We distinguish these product features from the questions explored in outside research.
We'd rather show you six strong studies than stretch the truth across sixty. The science speaks for itself.
