SEK Acoustics 1

With this equipment set and two mobile phones or tablets you have a complete solution for 20 experiments on the generation, propagation and analysis of sound. A freely available app replaces the separate oscillator and function generator, while the included loudspeaker brings the phone's sound into the classroom and lets frequencies be determined directly on the device. The set combines a tuning fork with resonance box, a slinky spring, a drum, a sound level meter and further accessories, all packed in a fitted storage box for classroom use.
