    Blast-induced hearing loss (BIHL) is a significant issue affecting military personnel and civilians due to exposure to high-intensity impulse noise.

  • 2

    A new compressed-air blast mouse model was developed to study BIHL, allowing for reproducible and quantifiable auditory injury.

  • 3

    Local delivery of 7,8-dihydroxyflavone (7,8-DHF) via nanoparticles improved auditory brainstem response thresholds after blast exposure.

  • 4

    Histological analysis showed that 7,8-DHF treatment preserved inner hair cell density and reduced outer hair cell loss after blast.

  • 5

    The study supports the use of nanoparticle-enabled local TrkB activation as a potential strategy for treating BIHL.
