Sound or hearing stimulation is as important as visual stimulation. Creating vibrations with music can have a big effect on a learner’s ability to understand sound. As well as helping them to regulate sound, it helps with sound location and tracking skills.
The Wowee speaker (from Amazon) has long been the budget leader for this but if you are looking for a better sound and vibration to match, then the Bose is a great option. At a great price of £79.99, it has better sound quality than the Wowee. It also has Bluetooth connectivity, doing away with the cable, which so often gets in the way when using the speaker with resonance boards. Great quality, great sound, really portable and for Bose products, a great price.
