Hi there, I am currently working on a project that requires a waterproof subwoofer speaker (8 ohm) be hooked up to either a sine wave generator or a laptop/computer of some sort, this is because I want to be able to play frequencies and generate tones such as resonants and sweeps etc. So I’m thinking maybe a computer might be better than a sine wave generator as I’m sure you can just download a sine wave generator onto one anyway (please correct me if this is wrong). The basics of the project is to have a waterproof subwoofer speaker installed into the bottom of a crystal clear plastic pail/bucket then to place water and another medium such as glitter or dyes into the pail and then generate tones, my hope is that the glitter or dyes will make visualising what is going on in 3D space easier when sound is being generated by the speaker. I’m sure your all familia with the chladni plate experiment, this would be similar but instead of a flat plain you would be able to see the sound in three dimensions and maybe I can find those frequencies that spontaneously order the grains into patterns like in the Chladni Plate experiment but in 3D. So please can someone help me by pointing me in the right direction in regards to what I would need to connect the speaker I have to either a sine wave generator or a computer? This is my first post on this forum so please bare with me if this is a bit long winded or not listed in the right place. Thanks all
