Dear Eric,
there is an alternative with just one smartphone and earbuds suggested by the NPL, https://www.npl.co.uk/measurement-at-hom...ilet-rolls, and utilised by Physics in Advent on December 3, 2020, see https://youtu.be/wUAFem8eEKI and https://youtu.be/-8MO0Uacn5w
Would this work for you?
Best regards,
Jens
