BUZUD Hearing Aid W6

Technical Specifications

Clinical Indications

• Mild to moderate sensorineural hearing loss (SNHL) in adults — pure-tone average (PTA) 26–70 dB HL across 500 Hz–4 kHz
• Age-related hearing loss (presbycusis) — gradual high-frequency SNHL in adults aged ≥50
• Noise-induced hearing loss (NIHL) — permanent SNHL following occupational or recreational noise exposure
• Post-medical management hearing loss stabilised after otological treatment (e.g. post-otitis media, post-ototoxic drug exposure)
• Patients requiring discreet, app-controlled amplification with Bluetooth audio streaming capability

Community Consensus: Clinical Q&A

Q: What degree of hearing loss does the W6 address — and who should see an audiologist first?
The BUZUD W6 is indicated for mild to moderate hearing loss, corresponding to a pure-tone average of 26–70 dB HL. Individuals with severe (71–90 dB HL) or profound (>90 dB HL) loss require a higher-powered hearing aid and should be assessed by a registered audiologist or ENT specialist before device selection. A baseline audiogram is recommended before purchasing any hearing aid, as it establishes the degree and configuration of loss and confirms whether amplification alone is appropriate — conductive hearing loss (e.g. from middle ear effusion or otosclerosis) may be surgically correctable and should be excluded before fitting an amplification device.

Q: How significant is the 19.7 dB equivalent input noise (EIN) level for daily use?
EIN of 19.7 dB SPL is the level of internal electronic noise the microphone system introduces — lower EIN means quieter background noise during amplification. The IEC 60118-0 standard specifies EIN as a key performance indicator for hearing aids. A value of 19.7 dB is clinically acceptable for mild-moderate loss fitting; premium audiological-grade devices may achieve 15–18 dB EIN. For typical daily listening environments (conversational speech, television, telephone), this EIN level is unlikely to be perceptible above ambient noise.

Q: Does the W6 require fitting by a registered audiologist in Singapore?
The BUZUD W6 is an HSA-registered hearing aid. In Singapore, hearing aids are classified as medical devices and may be purchased without a mandatory audiologist prescription — however, the Singapore Association for the Deaf and the Allied Health Professions Council strongly recommend audiological assessment and fitting verification before use. Proper fitting (gain verification via real-ear measurement, or at minimum audiogram-matched programming) significantly improves speech intelligibility outcomes. EMIS recommends all W6 purchasers undergo a baseline audiogram before initial fitting adjustment.

Q: What is the OSPL90 and why does 105 dB matter for safety?
OSPL90 (Output Sound Pressure Level at 90 dB input) is the maximum output the hearing aid can produce — the "ceiling" of amplification. At 105 dB SPL, the W6 provides sufficient gain headroom for moderate hearing loss without risking acoustic trauma in listeners with mild loss. The IEC 60118 standard requires OSPL90 to be measured and disclosed to prevent over-amplification injury. For context, hearing damage risk increases significantly above 85 dB SPL with prolonged exposure — the W6's maximum output should be managed via app gain settings to match the individual's audiogram and comfort thresholds.
