Nor would you be likely to find any physicists who would say there could be no effect.
I know what you mean, this is the type of argument used by the "catastrophic" Global Warming advocates - they all point out that C02 is a greenhouse gas therefore it must have an effect. This is all true but it is the relative size of the effect compared to other factors which is actually relevant. No doubt the kind of shampoo one uses might have some effect on the sound quality too.
