Functional Characteristics
Stable Broadband Noise Signal
The stable output sound level and spectrum are crucial for the reliability of test data. The frequency range of the sound source is as high as 20KHz, and the frequency stability and sound pressure stability are very superior, reaching the metrological level and meeting the needs of the site and laboratory.
LED Display Screen
The bright LED display screen allows for clear observation of the screen's content even in various complex environments. The instrument is equipped with a TF card interface and USB interface, making it easy to read and play externally stored audio data files. The integrated audio input interface allows for direct playback of external analog audio signal inputs, such as input audio from a PC or mobile phone, with an infrared receiver for remote control of the sound source.
Can output pink noise, White noise, Sine signal, and Custom Audio Signal
It can output commonly used acoustic testing signals in testing and metrology, such as pink noise, white noise, and sinusoidal signals, as well as user-defined audio signals, ensuring compliance with the diverse needs of acoustic testing personnel.
Suitable for free and reverberant sound fields
In laboratory applications, different sound field environments are involved, and the SVLab218 reference sound source can be used for both free field and reverberant sound fields, both of which have excellent performance.
