External auditory canal photobiomodulation and audio therapy device

A method of providing photobiomodulation and audio therapy to a human using two therapy devices each having a housing configured to be inserted into an external auditory meatus of a respective one of a pair of human ears, wherein each of the housings carries at least one irradiation source and at least one speaker, the method comprising:

• inserting one of the therapy devices into the external auditory meatus of one of the pair human ears such that at least a portion of a radiation emitting surface of the at least one respective irradiation source faces at least a portion of dermis of the external auditory meatus of the one of the pair of human ears beneath which at least one of a first arterial branch and a first peripheral nerve branch of at least one cranial nerve is located, and such that acoustic waves exiting the at least one respective speaker pass through at least one opening in the respective housing and move through the external auditory meatus toward a tympanic membrane of the one of the pair of human ears,
• inserting the other of the therapy devices into the external auditory meatus of the other of the pair of human ears such that at least a portion of a radiation emitting surface of the at least one respective irradiation source faces at least a portion of dermis of the external auditory meatus of the other of the pair of human ears beneath which at least one of a second arterial branch and a second peripheral nerve branch of the at least one cranial nerve is located, and such that acoustic waves exiting the at least one respective speaker pass through at least one opening in the respective housing and move through the external auditory meatus toward a tympanic membrane of the other of the pair of human ears,
• controlling the at least one irradiation source of each of the two therapy devices to irradiate the respective at least one of the first and second arterial branches and the first and second peripheral nerve branches of the at least one cranial nerve through the at least a portion of dermis of the external auditory meatus of each of the pair of human ears, and
• simultaneously or alternatingly with controlling the at least one irradiation source of each of the two therapy devices, controlling the at least one speaker of each of the two therapy devices to produce the acoustic waves.
