Craftsmanship Note: CICADA Jammers
Crafted with precision utilizing Multi Jet Fusion Printing with PA-12 Nylon Resin, featuring a precision high quality sand-blasted finish. Housed in a rugged enclosure, Cicada seamlessly harmonizes aesthetics with functionality.

CICADA is a robust 39 transducer jammer designed for larger offices or clients needing heavy-duty protection. Features DGC technology for superior security and privacy.

In our transition towards larger and more potent jamming solutions, we proudly introduce the CICADA Jammer—a robust, highly portable anti-recording Ultrasonic Jammer tailored to meet the discerning needs of clients seeking effective protection against eavesdropping and unauthorized recordings within vehicles and small offices, as well as those who wish to create their own HushBox jamming cabinets and enclosures.

Designed for versatility, the Cicada and Firefly offer the flexibility to be used as standalone devices or integrated into your own custom enclosures, effectively replacing the need for a separate HushBox. Both the Cicada and Firefly are adept at jamming electronic devices within enclosures with 100% efficacy, giving you the freedom to create your own secure HushBox setups for large meetings involving dozens of electronic devices. Whether used individually or as part of a larger security system, the Cicada and Firefly provide reliable and effective jamming capabilities, safeguarding your confidential communications and data.

Operational Prowess of Cicada

Grounded in strategic utilization of nonlinear effects inherent in microphones, Cicada deploys a diverse array of jamming signals across distinct bandwidths. The innovative approach involves collaboration of signals to form a comprehensive wideband signal injection array.

Differential Gain Control (DGC) Mechanism

Cicada incorporates a sophisticated Differential Gain Control (DGC) mechanism within its cutting-edge hardware. This mechanism allocates distinct gain coefficients to signals across different frequency bands, This innovative technology amplifies the transmission power of ultrasonic waves, systematically disabling every microphone within each electronic device. This mechanism ensures the effective thwarting of unauthorized recordings, setting a new standard in security protocols.

Models of CICADA

CICADA comes in two models:

  • Model 1: 27 Ultrasonic Emitter Variant
  • Model 2: 39 Ultrasonic Emitter Variant

Key differences include size, weight, acoustic interference output, transducer phased array configuration, battery power/capacity, and quantity of emitters.

Jamming Capability of Cicada

Cicada's signal effectively neutralizes microphones within a range of up to 5+ meters (or more) and effortlessly penetrates clothing. It counters traditional microphones and electronic devices capable of eavesdropping.

Key Features

  • Advanced Technology: Cicada employs sophisticated dual-wave Ultrasonic Microphone Jamming, emitting simultaneous stacked Sinusoidal and Square waves through three meticulously arranged arrays of 9 emitters, totaling 27 ultrasonic emitters.
  • Activation: Effortlessly activated through a chrome switch or wirelessly via remote control (RF SWITCH BY REQUEST)
  • Battery Power: Powered by an 18,000 mAh NiCAD battery (32,000 mAh for larger unit), ensuring an extended runtime.

Noise Level

Engineered for near-silent operation, the intentional creation of an audible wave enhances the jamming sweep's ability to overwhelm microphones and create a signal that cannot be reverse-engineered in post-processing software.

Primary Purpose

Privacy and Security: Cicada is purposefully designed to disable microphones and AI "Virtual Assistant" functionalities in vehicles and office spaces by means of Ultrasonic Jamming, ensuring privacy during sensitive conversations or discussions by neutralizing microphones contained within electronic devices.

Limitations and Recommendations

  • Physics Consideration: Variations in susceptibility may be observed among different microphone designs, impacting the jammer's effectiveness.
  • Operational Range: Cicada is effective in jamming devices more than 5 meters away, sometimes even more based on the specific microphone type and environment.
  • Surfaces and Materials: Ultrasonic noise may experience reflections off surfaces and encounter limitations in penetrating certain materials.
  • Optimal Deployment: For larger rooms, strategic deployment of multiple devices enhances the countermeasure against potential eavesdropping activities. Comprehensive testing is recommended, especially in very large meeting rooms and offices.

Compatibility with AI-enabled Devices

Cicada effectively counters a broad spectrum of AI-enabled products, including Google Nest, Amazon Alexa, Echo, Sonos, and various vehicle smart assistants. These jammers proficiently disable microphone functions with 100% efficacy if precisely targeted.

Technical Specifications

  • Interference Intensity: 27 Ultrasonic Emitters × 128-132 dB / (5-10 Meters*) 300 Degree coverage: 9 x emitters to the front. 9 x emitters to the right of device. 9 x emitters to the left of device. Acoustic Interference Output: 4W


    39 Ultrasonic Emitters × 128-132 dB / (3-5+ Meters*) 300 Degree coverage: 9 x emitters to the front. 15 x emitters to the right of device. 15 x emitters to the left of device. Acoustic Interference Output: 6W

  • Jamming Capability: Neutralizes microphones within a range of up to 3-5+ meters (or more*).
  • Time to full Charge: 9 hours.
  • Battery voltage: 3.7 V.
  • Charge Voltage: 5 V.
  • Battery Life: 5 h.
  • Ultrasonic Interference angle (per Transducer): 80°.

*This jamming distance is based on our own testing, users will find in some instances contingent on environment, they can achieve jamming at a much greater distance with a greater reach as ultrasonics bounce off each other, the general rule of thumb is, the more transducers + Drivers in an array = the further and wider the jamming effect will reach.

Safety Precautions

Adherence to the following safety precautions is crucial for responsible and secure utilization of the Cicada Jammer:

  • Avoid contact with water and areas of high humidity.
  • Safeguard the device from dripping and splashing water.
  • During cleaning, use solely dry materials, ensuring protection from rain.

Temperature Considerations

  • Refrain from using the device in areas with extreme temperatures.
  • Operate in an environment with a temperature between 0° and 45° C.
  • Exercise caution to avoid installing the device near heat sources.

Electricity Conduction

  • Steer clear of contact with parts that conduct electricity.
  • Do not remove the cover or casing to mitigate the risk of electric shock.

Hearing Protection

  • Maintain a safe distance from the device to prevent potential hearing damage. Prolonged use at high volume may result in hearing impairment; therefore, deploy Cicada with care and at appropriate times for the intended purpose. Your safety is of utmost importance, and these precautions are meticulously outlined to ensure the responsible and secure utilization of the Cicada Jammer.

In instances where Cicada or other anti-recording jammers are employed to disrupt microphone functionality within a designated area, it is imperative to acknowledge the constraints dictated by the principles of physics. Variations in susceptibility among different microphone designs may affect the jammer's efficacy. Consequently, the maximum operational range of the jammer may exhibit significant fluctuations contingent upon the specific microphone type. Furthermore, the ultrasonic noise generated may undergo reflections off diverse surfaces and confront impediments in penetrating most materials to substantial depths. To optimize privacy safeguarding during meetings, deploying multiple devices strategically within larger rooms is recommended. This approach ensures a more comprehensive and effective countermeasure against potential eavesdropping activities.
