- ULTRASONIC EXPOSURE + VOICE IMITATION = 100% microphone jamming
- HIGH SUPPRESSION POWER AND ACTION RANGE. This microphone blocker emits a very powerful ultrasonic signal (not less than 120 dB) which suppresses microphones at a maximum distance of 7 m (23 ft). The distance is shortened to 2 m (7 ft) for newest iPhone models with an improved noise cancelling system.
- SOPHISTICATED ULTRASONIC PATTERN that is effective against newest noise-canceling and water-resistant phones. Range and effectiveness can be increased when used with one or more external ultrasonic speakers (sold separately).
- 7 ULTRASONIC TRANSDUCERS that ensure protection in front and across the device. Use it as a "virtual wall" to protect yourself from recording devices.
- CAN BE USED ABSOLUTELY SILENTLY but best results achieved when ultrasonic and white noise interferences are combined.

Dictaphone jammer BugHunter BDA-3
Microphone suppressor "DAudio bda-3 Voices" with 7 ultrasonic transducers with an improved jamming system and an option to connect up to 4 additional external ultrasonic speakers. It has 2 additional transducers on the top panel that create a "virtual wall" for maximum protection against sound recording devices. Device blocks most types of microphones and dictaphones (including professional ones) in the range of up to 7 meters (23 ft) and at even greater range when using the external ultrasonic speaker. For a maximal efficiency of ultrasonic interference it is advised to engage "TURBO mode". Acoustic interference volume can be adjusted (and even turned off for a completely silent operation), power can be supplied through a 110/220V power source or built-in battery.
Ultrasonic speaker is not supplied with the suppressor and is sold separately. If needed, you can attach two speakers via a regular splitter for a 3,5 mm jack.
Operation Principles
Device generates ultrasonic signal through 7 transducers. Frequency is determined by a micro-controller and variates according to a specially developed algorithm. Ultrasonic signal affects recording paths of spyware which results in them fixating only indiscriminate noise in which conversation can’t be distinguished.
Besides, a powerful speaker creates acoustic speech-like interference which destroys the meaning of the conversation: because of it spyware fixates only muttering, restoring the conversation becomes physically impossible. Acoustic interference is generated randomly so it can’t be filtered out even with special equipment.
Anybody, even a non-professional can use the device. Just point the transducers in a direction of an expected location of recording devices and turn it on. Adjust the volume level of the acoustic signal if needed. Notice that you can make your protection more reliable by using an additional ultrasonic speaker.
