Plasticity is a pitch discrimination game — that is, a game which tests and improves your ability to distinguish between similar sounds based on their frequency (pitch). You hear two sounds, which may have the same or different frequency (with 50-50 probability) and your job is to say whether they have the same frequency or different frequencies. At first, the differences are fairly obvious, but as you level up, they become smaller and smaller, which makes your job harder.
Plasticity can be a fun game to play (at least, if you believe some of my friends). In addition, it might be helpful if you want to improve your pitch discrimination skills – for example, if you’re a musician.
Plasticity is based on the Firefox Audio API and, as such, requires Firefox 4 or higher. Plasticity uses the HTML5 Web Audio API. It has been tested to work (at least) in recent versions of Chrome, Firefox and Safari – including mobile devices (in the latest release).
I wrote Plasticity to treat my tinnitus (a phantom sound in my head). The idea was to re-wire the auditory cortex in my brain through repeated training in order to change my perception of the tinnitus sound. The name “Plasticity” refers to cortical plasticity – the ability of the cortex to reorganize in response to stimuli. Did Plasticity help my tinnitus? Well, I no longer have a tinnitus problem, though I am not sure to what extent Plasticity contributed to the improvement. If you have tinnitus (especially pure-tone tinnitus), you might as well give it a try. Here are some tips on how to use Plasticity for tinnitus.
