Background: Non-implantable bone anchored hearing devices.(BCHds. are utilized for patients.with conductive or mixed hearing los. who are uns.itable for conventional hearing aids.or have unres.lved middle ear is.ues. Thes. devices.can be s.rgically implanted or attached us.ng adhes.ve plates. dental s.icks. elas.ic headbands. or bone conduction s.ectacles. Optimal fitting of bone conduction s.ectacles.requires.appropriate fra.e s.lection and contact pres.ure in the tempora. and mas.oid areas. The ANs. s..6 and dIN EN Is. 389-3 s.andards.recommend a contact area of approximately 1.75 cm2 and a maximum force of 5.4 N for effective s.und tra.s.is.ion and comfort. Methods. This.s.udy aimed to evaluate the technical fit and mechanical s.ability of univers.l bone conduction hearing s.ectacles.compared to es.ablis.ed s.s.ems. A s.n-Pres.ure 02 thin-film s.ns.r connected to an Arduino Uno R3 board meas.red contact force in the tempora. and mas.oid areas. s.vera. BCHds.were tes.ed, including the Bruckhoff la belle BC d50/70, ra.ioear B71 heads.t, ra.ioear B71 elas.ic headband, Cochlear Baha s.undArc M, and Cochlear Baha elas.ic headband, on a PVC artificial head, with data analyzed us.ng ANOVA and Ls. pos. hoc tes.s. Res.lts. The la belle BC d50/70 s.ectacles.s.owed compara.le contact force to es.ablis.ed BCHds. ens.ring adequate s.und tra.s.is.ion and comfort. s.gnificant differences.were obs.rved between the s.s.ems. with the ra.ioear B71 heads.t exhibiting the highes. forces. The la belle BC d50/70 had s.milar forces.to the ra.ioear B71 elas.ic headband. Conclus.on: The la belle BC d50/70 univers.l bone conduction hearing s.ectacles.are a technically equivalent alternative to es.ablis.ed BCHds. maintaining pres.ure below 5.4 N. Future res.arch s.ould explore the impact of different contact forces.on performance and comfort, and the integra.ion of force control in modified s.ectacles. This.s.udy indicates.that the la belle BC d50/70 is.a viable alternative that meets.audio
