A unique speech protector in the form of a classic wooden speaker. The EO-3 PRO speech protector is discreet and very elegant. It does not interfere in any way with the flow of the meeting, while keeping you within range.

The handset is suitable for permanent placement, for example in a meeting room. It protects very effectively against classic eavesdropping and bugs, but also against eavesdropping through the wall or with a laser microphone.

  • • Completely discreet, it looks like a classic speaker so it doesn’t interfere with the flow of the meeting.

  • • It generates ultrasonic noise to effectively protect you against bugs and microphones.

  • • The acoustic noise generator can protect against stethoscopic and laser microphones – you can even record and generate your own voice.

  • • Several adjustable modes to prevent eavesdropping and bugging.

  • • It guarantees a discreet and completely secure meeting from which no information is leaked.

The EO-3 PRO speech protector offers unique protection in the form of a combination of ultrasonic and acoustic noise. The ultrasonic noise will ensure microphones within a range of 5 meters will be drowned out and unable to make any recordings. Acoustic noise, on the other hand, completely eliminates the risk of recording with a conventional analogue dictaphone, stethoscope or laser microphone. You can be assured of a truly safe yet discreet meeting. This is what makes the EO-3 PRO eavesdropper and bug jammer absolutely unique.



  • Digital and analogue voice recorders
  • Dictaphones in mobile phones
  • Remote laser eavesdropping through windows
  • Built-in and directional microphones
  • Eavesdropping via stethoscope

EO-3 PRO Discreet Speech Protector

Parameters

Functions of ultrasound

The Ultrasonic Noise Generator primarily protects against all eavesdropping and bugs that record sound using a microphone. It is taken care of by 25 ultrasonic generators with an intensity of 120 dB. This creates a strong ultrasonic barrier for microphones. The resulting recording will be unusable because the person will not understand at all and your communication will remain protected. The big advantage is that the ultrasound noise is not audible to the ear, so it does not disrupt the meeting.

Easy to use

The advantage is that our discreet speech protector EO-3 PRO does not have to be installed or set in any way. You simply put it in place, connect it to the electricity and turn on the protection against eavesdropping. Then activate the ultrasonic noise. Choose the acoustic noise as loud as it suits you. But it must overlap your conversation. You can discreetly control the EO-3 PRO speech protector with a remote control.

Acoustic noise

The acoustic noise function is important, it protects you especially from eavesdropping through the wall, by a third person or using a laser microphone. Acoustic noise is a mixed voice that is randomly generated and overlays your conversation. It provides double protection, in combination with ultrasonic noise it is the best without competition. Speech protector can even mix your own voice, which you can record before the meeting. It will protect you from the methods of modern forensic record cleaning.

Instructions for use

Place the EO-3 PRO speech protector where you expect to find possible eavesdroppers and bugs. You can place it directly on the meeting table, because it looks like an elegant loudspeaker – it is discreet and no one will know it is a speech protector. The effective range of ultrasonic and acoustic noise cancellation is up to 5-30 metres. Simply operate the jammer with the remote control, using the following modes.

  • A: Silent Ultrasound – suppresses high quality voice recorders

  • B: Device off – the protection is switched off

  • C: Ultrasonic and Silent Acoustic Noise – is the main operating mode that allows you to act comfortably and protects you against all types of eavesdropping devices

  • D: Ultrasound and loud acoustic noise – maximum protection mode, used when you need to fully protect information at the cost of negotiation comfort

If you decide to record your own voice into the speech protector to generate acoustic noise, it’s not complicated. Just press the volume button. The speech protector will then start recording your conversation. We recommend a conversation of at least 5 minutes on a non-binding topic. The speech protector will then use this conversation to generate acoustic noise in the form of random words. This overlays the conversation. This is a unique solution found in all of our EO jammers.

Important!

  • • The use of an ultrasonic generator to drown out microphones in close proximity has certain limitations arising from the laws of physics. Some microphone designs are more prone to jamming than others, so effectiveness can vary by microphone type. Depending on this, the maximum effective range of the generator can fluctuate several times. In addition, the generated ultrasound is reflected from the surface and is not able to pass through most materials to an excessive depth. For this reason, it is recommended to use a sufficient number of devices and then place them appropriately in the given room to ensure the best possible privacy during negotiations and meetings.

  • The highest possible quality of interference is achieved thanks to the Acoustic Noise function, which allows you to record your own voice and cover your conversation with it. The recorded voice is then randomly generated, creating a sound barrier against eavesdropping by a stethoscope microphone or a laser eavesdropper. In addition, it protects against the most modern methods of forensic cleaning of the voice recording.

  • • Although the device does not guarantee 100% muting efficiency, it surpasses competitive solutions. Thanks to its configuration, it guarantees high efficiency against microphones on devices such as voice recorders, bugging and seismic microphones, microphones on computers, headsets, cameras and mobile phones.
