Snore Sensors for PSG Systems – Microphone & Piezo Technology

Snore sensors for sleep diagnostics. Accurate snoring detection is a critical parameter for comprehensive sleep-disordered breathing assessment, aiding in the identification of Upper Airway Resistance Syndrome (UARS) and improving respiratory event scoring. Our sensors use two advanced technologies to capture snoring events objectively.

Why Snore Monitoring Matters in Sleep Studies

Snoring is more than just an acoustic phenomenon—it’s a key clinical indicator. A dedicated snore sensor provides:

• Objective snore documentation: Quantifiable data on snoring frequency and intensity for sleep reports
• Enhanced respiratory event scoring: Snore signal correlation aids in identifying hypopneas and RERAs
• Treatment efficacy tracking: Objective measurement of snoring reduction with interventions like CPAP or oral appliances
• Differentiation from artifacts: Helps distinguish true snoring from other noise sources

Understanding Snore Sensor Technologies

We offer two complementary technologies for snore detection, each with distinct advantages:

Microphone Snore Sensors – Vibration Detection

Our microphone snore sensors utilize a highly sensitive microphone element to capture minute vibrations on the skin’s surface of the neck, directly associated with snoring sounds. Key benefits include:

• High sensitivity to subtle vibrations
• Clear signal output – transduces vibrations into clean, low-noise electrical signals
• Advanced comfort – features flexible TPU cables that reduce drag and minimize patient discomfort
• Easy placement – affixes to the neck with medical tape

Piezo Snore Sensors – Crystal-Based Detection

Our piezo snore sensors use a high-precision piezoelectric crystal element that generates a voltage signal when mechanically stressed by skin vibrations. Advantages include:

• Direct vibration-to-signal conversion – avoids ambient noise pickup common with air-coupled microphones
• Exceptional durability – piezoelectric elements are robust and reliable
• Consistent performance – unaffected by ambient room noise
• Ideal for multi-system labs – one sensor works across multiple platforms   
• Snore Sensors by Compatible System

• Microphone vs Piezo: Which Snore Sensor Is Right for Your Lab?

  Wondering about the difference between microphone and piezo snore sensors? Here’s a quick comparison:

  Feature	Microphone Sensor	Piezo Sensor
  Detection method	Skin vibration via microphone	Direct mechanical stress on crystal
  Ambient noise sensitivity	Minimal (contact-based)	None (direct vibration)
  Signal type	Electrical from vibration	Voltage from crystal deformation
  Best for	Labs wanting advanced sensitivity	Multi-system labs, research
  Cable option	Flexible TPU available	Standard 2.0m cable

  Snore Sensor Placement and Signal Quality

  For optimal snoring detection, proper placement is essential. Our sensors are designed to be affixed to the patient’s neck with medical tape, positioned over the larynx or trachea. This location captures the most direct vibration from snoring while minimizing interference from other sounds. The low-profile design maximizes patient comfort for overnight studies.

  How to Choose the Right Snore Sensor

  When selecting a snore sensor for sleep studies, consider:

• Your PSG system: Does it require keyhole (Alice/Grael) or 1.5mm DIN (PSG-1100/Cadwell/Compumedics) connectors?
• Technology preference: Microphone sensors offer advanced sensitivity; piezo sensors provide direct vibration detection and multi-system compatibility
• Patient comfort needs: Our TPU-cable options reduce drag and improve comfort for sensitive patients
• Multi-system labs: If you have multiple equipment brands, our piezo sensor works across PSG-1100, Cadwell, and Compumedics systems
