Microphones
MP34DB02TR is a noise canceling Microphone featuring bottom port design. It is best used with hands-free applications, such as VoIP, speech recognition, hearing aids, and sound recognition. It features an improved directivity and a wide dynamic range that provides improved acoustic performance. The MP34DB02TR is designed to provide low self-noise and high sensitivity while maintaining a good level of linearity and accurate high frequency reproduction.
Application Field:
The MP34DB02TR microphone is suitable for a wide range of applications, such as speech and voice recognition, teleconferencing, VoIP and broadcasting. It can also be used for hearing aids, hands-free control devices, and speech recognition systems. In addition, the microphone can be used for sound measurement, acoustic testing, and portable recording. Due to its high sensitivity and low distortion, the MP34DB02TR is suitable for use in high-end audio recording environments.
Working Principle:
The MP34DB02TR employs a bottom port design which eliminates false signals such as wind noise. Its transducer is made up of an acoustic diaphragm and a backplate. When soundwaves enter the capsule, the diaphragm vibrates towards the backplate and causes a change in the electrical properties of the transducer. This change is then converted into an electrical signal and sent to the output.
The MP34DB02TR also features a wide dynamic range which allows it to capture both faint and loud sounds without distortion. This feature ensures that voices and other sound sources are accurately reproduced. It also reduces the need for further signal processing and provides a clearer and more natural sound.
The MP34DB02TR has good linearity and a low level of self-noise which ensures that all sound sources are accurately captured. In addition, the microphone also has a wide frequency response which covers the entire audio spectrum and allows it to accurately capture all sound sources in a given environment.
The MP34DB02TR is a high-quality, noise-canceling microphone that is suitable for a wide range of applications. Its bottom port design eliminates false signals and its wide dynamic range ensures accurate sound reproduction. Its transducer, linearity, low self-noise, and wide frequency response make it a great choice for high-end audio recording environments.
