Martin Horejsi, from NSTA Recommends, has collected data with Go Direct Sound just about everywhere on campus. In his review, “The Vernier Go Direct Sound Sensor: See Sounds in a New Light (Bluetooth),” Martin discusses the importance of sound safety, provides a brief history of the decibel, and details various investigations using Go Direct Sound.
Martin concludes his experience by saying:
“The Vernier Go Direct Sound Sensor is a welcome addition to the family of bluetooth sensors giving our students a tremendous visual inspection into the world of sound. And it really does put a face on those eardrum-generated electrical pulses bouncing around inside their brains. Soon the students will be saying things like, ‘I thought that sound looked loud.’ And it will make perfect sense.”
With Go Direct Sound, students can capture and evaluate waveforms. Exploring the waveforms of various musical instruments has never been easier. Students can also use the sensor to measure wave amplitude and sound intensity level at the same time during decibel scale investigations. They can even take the sensor outside the classroom to measure sounds in their natural environment.
The sensor is part of the complete Go Direct family of sensors that offers teachers and students maximum versatility to collect scientific data either wirelessly or via a USB connection. These affordable sensors can be used in more than 300 teacher-tested experiments developed by Vernier and are supported by free graphing and analysis software, the Graphical Analysis™ 4 app.
