You cannot delete your account yourself if you have sounds uploaded to your account. In their own words: "Because you have sounds on freesound, deleting your user is not a trivial task. As such, we ask you to please contact the administrators via the Contact Form. They will help you with the deletion of your account....". Alternatively - you can go through all your sounds, delete them one-by-one, and then delete your account.
