Silent Sound Technology

Silent sound technology is an innovative way to communicate without the use of lips or voice. Developed at the Karlsruhe Institute of Technology, this technology uses an electrical pulse to convert a message into sound, which is sent to the other end without causing any disturbance. This technology helps you converse in public places where noise pollution is an issue.

Silent Sound Technology


Electromyography is a technique that monitors the tiny movements of the skeletal muscle during speech. These signals are then converted into electrical pulses that can be transmitted to the other end of the line. It is a very sensitive technique that needs a muscle membrane potential that is between -90 mV to produce speech.

Electromyography is not only useful in recognizing speech in noisy environments, but it is also useful in very quiet environments. The electrical potentials generated by the speech articulation system are captured using electrodes attached to the skin. After recording the signal, pattern-matching algorithms can reconstruct the movement of the articulatory muscles. The result is a recognized speech output, which is then synthesized and re-encoded as text.

The electrical EMG signals generated by the SVR can be processed in a variety of ways. The first method involves the use of a reference electrode that identifies the speaker's reference potential. The second method utilizes electrical EMG signals, which are amplified using specially-designed amplifiers. These amplifiers are able to produce the most accurate and reliable results, even in situations where the patient is not exercising any muscles.

Electromyography is an important component of Silent Sound Technology. It allows the technology to translate words into any language, even if the recipient does not speak the same language as the source. It also allows the translator to silently utter a word in their language. It can then translate into the language of the receiver. In this way, people living in different languages can communicate in their native language.

Silent sound technology is a great option for people who lost their voices or are deaf. It helps these individuals communicate via telephone, hand over sensitive information, and do business. It can also be a great advantage for professionals who travel. It can also eliminate the need to shout to communicate in crowds.

Lip movement detection

A new technology has been developed that can detect lip movement and convert it into computer-generated speech. It was unveiled at the CeBIT fair on Tuesday by the Karlsruhe Institute of Technology. The system is able to detect the tiniest movement of your lips and converts it into electrical pulses that are transmitted to the other end of the conversation without disturbing the other party. This technology has the potential to make people with voice loss speak in their own language and make silent calls.

The method relies on lip-shape-based feature extraction and the use of acoustic envelope signals from the 4-8 Hz frequency range. This method entrains lip movements, which is useful for noisy environments and crowded spaces. Its use in speech perception is associated with the recruitment of the auditory cortex, where theta oscillations play a functional role in information flow.

Noise pollution reduction

A new method is reducing noise pollution through a ringlike structure. The structure is created using 3D printing and has mathematically perfect specifications for noise cancellation. The technology can be used in any environment and can be customized to block a variety of sounds. The researchers developed the technology to combat urban noise pollution in Boston. They studied how the noise pollution levels in Boston are impacted by a variety of sources, including airplanes flying overhead, MBTA trolleys, and building appliances.

The goal of the technology is to interfere with the sound waves that are being transmitted from loudspeakers. To achieve this, the metamaterial must be made in a way that sends back the incoming sound. Using 3D printing, they created a structure that could silence the sound of a loudspeaker.

Silent sound technology was developed by the Karlsruhe Institute of Technology. The new system allows people to communicate without raising their voices. Instead, an electrical pulse is converted into sound and transmitted to the other end without the use of lips. As a result, the technology reduces noise pollution in public areas. In addition, it also allows people to communicate without interrupting others. In the future, it will be possible to use technology to make cars quieter.

Noise pollution is a serious problem that can affect people's health. It affects their ability to sleep and can cause a host of other problems. For example, excessive noise increases a person's heartbeat by 4%. In addition, the noise can affect the person's mental state and affect their ability to function. It is no wonder that tech companies are trying to find ways to drown out unwanted sounds.

In urban areas, freeways are the most common source of noise pollution. Traditional noise mitigation methods include barrier walls and earthen berms. These are effective at reducing sound pollution but are costly to construct and maintain. Another issue is graffiti. Despite their effectiveness, barrier walls and earthen berms can only reduce noise by 10 to 15 decibels.

Silent sound technology is a low-cost solution for reducing noise levels in silence zones. This technology uses a microcontroller, RF module, and GSM to interface with sound systems. The microcontroller is programmable and can be used to store codes for future use. Moreover, the system uses a linear power supply to minimize power requirements.

Another solution for reducing noise pollution is to install external walls with high noise reduction. The National Construction Code lays out specific guidelines for acoustic properties in multi-residential buildings. While heavy, dense materials are recommended for sound insulation, lightweight alternatives are also available. Interior walls are also effective at reducing noise pollution.
