The Term-LAB USB system is a precision measurement instrument that utilizes a combination of hardware and software technology to measure the sound intensity inside of a vehicle. (Term-LAB requires a PC or laptop running Windows XP for operation.) Term-LAB is based on award winning innovative technology that changes the way sound is measured inside a car. The heart of the system is the Precision SPL Sensor that attaches to the inside of the windshield with two suction cups. This attachment method alleviates the need for bulky microphone stands. In addition, the Precision SPL Sensor is based on Sensor Technology instead of the antiquated microphone capsules that have been used in the past.
