Is this trial a fit for you?

Likely a good fit

Adults aged 18–60 with insomnia symptoms (PSQI >5 and/or ISI >15) who can attend in-person polysomnography visits and meet eligibility criteria are the intended candidates.

Probably not a fit

People with moderate-to-severe obstructive sleep apnea (AHI >15), significant hearing loss, epilepsy, current use of sedative-hypnotics or neurostimulation devices, psychiatric disorders, shift work, or pregnancy are unlikely to benefit or be eligible.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This single-arm, prospective pre-post interventional study will deliver nightly personalized sound-frequency therapy to adults with insomnia for 12 weeks. Full-night polysomnography is performed at baseline and after 12 weeks to measure changes in sleep stages, total sleep time, sleep latency, and sleep efficiency. Secondary outcomes include PSQI, ISI, AHI, ESS, and measures of adherence, tolerability, and acceptability. Participants are recruited from patients and hospital staff at Hospital Canselor Tuanku Muhriz UKM in Kuala Lumpur.

Why it matters

Potential benefit: If successful, the therapy could improve objective sleep stages and subjective sleep quality without adding sedative medications.

How similar studies have gone: Previous small studies of auditory stimulation have shown increases in slow-wave activity and some sleep benefits, but personalized nocturnal sound-frequency therapy for insomnia is relatively novel and not yet widely validated.
