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.
Electromyography
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.
