Anyone has got an idea about a sound sensor ( that is really sensitive !) , i.e., can sense the sound levels of 20-25 db to convert them to electrical signals...or atleast how to make such a sensitive sensor...
Creating a Highly Sensitive Sound Sensor: Challenges and Considerations
In summary, the conversation is about creating a sound sensor that is highly sensitive and can convert sound levels of 20-25 db into electrical signals. The usual method is to use a microphone, but more information about the planned application is needed in order to provide better help. This includes the distance of the microphone from the sound source, the frequency range, and the sound pressure level. The planned application involves a distance of 10-15 meters and a frequency range of 500-6000 hz, with a sound pressure level of 20,000 µPa, which is the same level that the human ear is comfortable with.

a microphone is the usual way
a bit more info on your planned application would be helpful so those here could help you better :)
is the microphone going to be close or distant to the sound source ?
what distance ?
what frequency range ?

Distance may be 10-15 m and the frquency is the frequency of normal conversation i.e about 500-6000 hz and the sound pressure level is about 20,000 µPa, just the same that the human ear is comfortable with...davenn said:
Related to Creating a Highly Sensitive Sound Sensor: Challenges and Considerations
What is a Required Sound Sensor type?
A Required Sound Sensor type is a type of sensor that is designed to detect and measure sound waves in its surrounding environment. It is commonly used in scientific research and experiments, as well as in various industries such as automotive, aerospace, and healthcare.
How does a Required Sound Sensor type work?
A Required Sound Sensor type works by converting sound waves into electrical signals. The sensor contains a diaphragm that vibrates when exposed to sound waves, which in turn moves a coil or piezoelectric material. This movement generates an electrical signal that can be measured and analyzed.
What are the applications of a Required Sound Sensor type?
A Required Sound Sensor type has a wide range of applications, including noise pollution monitoring, acoustic research, and industrial process control. It is also used in medical devices such as hearing aids and cochlear implants, as well as in smart home technology for voice recognition and control.
What are the different types of Required Sound Sensors?
There are several types of Required Sound Sensors, including condenser microphones, piezoelectric sensors, and fiber optic sensors. Each type has its own unique properties and is suitable for different applications. For example, condenser microphones are sensitive to high frequencies, while piezoelectric sensors are better for measuring low frequencies.
What factors should be considered when choosing a Required Sound Sensor type?
When choosing a Required Sound Sensor type, factors such as sensitivity, frequency range, size, and cost should be taken into consideration. The specific application and environment in which the sensor will be used should also be considered, as well as any necessary calibration or maintenance requirements.
