A proof-of-concept trial by UK mobile operator O2 and software provider Mavenir found that nearly 90% of participants with hearing loss reported improved call clarity through a network-level audio optimization technology that requires no new device or app....
No actionable change — this is an early-stage industry proof-of-concept trial with no peer-reviewed data; audiologists should monitor developments but have nothing to act on clinically today.
Network-level audio optimization could become a low-barrier, device-agnostic way to improve phone communication for hearing-impaired patients, potentially complementing hearing aids without requiring any patient-side action.
- 01O2 and Mavenir ran a proof-of-concept trial of network-based audio optimization for phone calls.
- 02~90% of participants with hearing loss reported improved call clarity.
- 03The technology operates at the network level — no new device, app, or hearing aid required.
- 04Trial details (sample size, methodology, controls) have not been published in peer-reviewed literature.
- 05Broader rollout would depend on mobile operator adoption, not audiologist or patient action.
Approximately 90% of participants with hearing loss reported improved call clarity using the network-based audio optimization technology.
