Does sound travel differently in Kentucky bourbon than it does in other types of alcohol? Stanley A. Cheyne of Hamden-Sydney College pondered this question before the 177th ASA meeting in Louisville, Kentucky. Twenty or so types of whiskey later, he’d made some interesting discoveries, both about whiskey and about how distilleries measure alcohol concentration. This episode we interview him about his resulting article in Proceedings of Meetings on Acoustics, “Sound speed measurements in ethanol/water solutions and Kentucky bourbon whiskey.”
