Best Audio Jammer Solution from iSecus
Ultrasonic Mixing Jamming Technology Introduction
Based on CPLD/FPGA Chip embedded with encrypted algorithm, it generates ultrasonic mixing data model and exports ultrasonic signals, forming a harmonic effect to deceive the recording device. The microphone/pick-up can only receive the harmonic ultrasonic signal generated by the jammer, can not pick up the normal voice signal.
The recorded audio only plays noise, its content cannot be identified, and cannot be analyzed using technical means (the noise completely covers the speech).
Effectively Block Unauthorized Microphone/Recording Devices to record your speech content!

FAQ related to iSecus Ultrasonic Audio Jammers
Q1. Can iSecus ultrasonic audio jammers 100% prevent the audio recording from authorized voice recording devices?
Answer: If it is box type of audio jammer (AJB-331 & AJB-336) where cellphones are put inside the box, Yes, 100% Perfect jamming effect!
If it is camouflage type of con-tactless Audio Jammer (AJS-333, AJ-315W, AJ-316D), that’s difficult to promise 100% jamming effectiveness. Because factors as distance, angles, power consumption, shielding affect the performance. But the performance of iSecus Audio Jammers is far superior to many other similar products in the market, concerning jamming effect, quietness and user-feeling experience, workman craft and quality. They are designed for high-end users. You will get what you pay.
When using ultrasonic audio jammers, it is necessary to understand the physical properties of ultrasonic and its limitations. Ultrasonic wave has the characteristics:
When encountering hard objects, it will be reflected; When encountering software objects, it will be absorbed.
Therefore, please try to avoid special obstacles between the jammers and target recording devices. Meanwhile, please consider suitable qty of jammers and proper placement to get the best protection of the conversation.
Q2: What is the jamming coverage area of iSecus camouflage audio jammers? Which one has the longest jamming distance? Which one is the best audio jammer?
Answer: The jamming angle and jamming distance for each model, please refer to the datasheet of each model. In our collection, target application determines the suitable models to use. Several typical common misunderstandings from FRESH Users:
1). Do you have longer-distance jamming devices?
—We can reach longer jamming distance performance by making the jammer in bigger size and bigger power output. But this will lead ear pressure which gives not good user feeling or can be found it is a jammer.
2). Do the jammers jam the whole room or whole area?
—The audio jammer is used to jam where there are humanbeings who would take unauthorized recording devices. Whom to jam, depends on where the jammer is put and whom the jammer angles are covered. The principle of ultrasonic audio jammer is to deceive recording devices’s microphone by sending ultrasonic wave. So it is also called microphone jammer.
Q3: How are your ultrasonic audio jammers handling the new mobile phones ? such as Iphone 15 and up and Samsung S22 and up ?
Answer: The logic of our audio jammer is to jam the microphone of cellphone through ultrasonic technology. It is different than white noise generator.
Concerning AJB-331 and AJB-336, within the box, no matter which brands/which models cellphone, it is 100% jamming performance.
Concerning AJS-333, AJ-315W and AJ-316D these camouflage jammers, we have tested them. Their jamming performance on Iphone 13, iphone 14 and Iphone 15 is similar, no big difference.
Q4: How far can AJS-333 jam on the cellphone? Why the jamming effects on different cellphones are varied?
Answer: The position and number of microphones in different cellphones, as well as the quality of the microphones themselves, are quite different. Some cellphone microphones have strong anti-interference energy, or the cellphones themselves have certain noise filtering algorithms, which are the factors that affect the jamming effect. Currently, jamming effect on android phones is much better than Iphone.
AJS-333 is a speaker shape audio jammer, which supports 3 sides (270 °) jamming angle. When the cellphone microphone is targeting at jammer, here are the test result on jamming distance:
XIAOMI 12 Standard: Around 8 meters
IPHONE 13 Standard: Around 2 meters
HUAWEI MATE 40 Standard: Around 3 meters
Q5: What is Ultrasonic Jamming Technology
Answer: Based on CPLD/FPGA Chip embedded with encrypted algorithm, it generates ultrasonic mixing data model and exports ultrasonic signals, forming a harmonic effect to deceive the recording device. The microphone/pick up can only receive the harmonic ultrasonic signal generated by jammer, can not pick up the normal voice signal. The recorded audio only plays noise, its content cannot be identified, and cannot be analyzed using technical means (the noise completely covers the speech).
Q6. Is the ultrasound technology harmful to human health?
Ultrasonic Technology has been widely used in many applications such as parking radar and B-ultrasonic. Ultrasonic is essentially a mechanical wave and does not radiate itself. However, it has strong directionality and high energy. When using it, try to avoid pointing it directly at the ear. It would cause ear pressure discomfort.
Q7. What are the main advantages and disadvantages of ultrasonic jamming technology, compared to white noise technology?
Advantages:
Ø Silent and Safe Jamming
Ø Better User Experience
Ø Wide Applications, especially governmental projects
Disadvantage: Cost is much higher!!!
