I have been looking for a while but I can't get them. In Blackstock's fundamentals of physiscal acoustics books there's a graph where you could get some values, but they can't fit in the formula you use.</p> <p>I know it has been asked before, but I still can't get reliable values.</p> <p>Kind regards</p> <p>Felipe. </p>
