Womb Heartbeat & Brown Noise: 4-Hour Sleep Session | Shushing + Heartbeat Sounds

Описание: 4-hour womb environment recreation combining three essential layers: maternal heartbeat (120-160 BPM), deep brown noise (20-200Hz foundation), and rhythmic shushing (womb-mimicking comfort). Scientifically engineered for newborn to 6-month infant sleep.

🔬 *AUDIO ARCHITECTURE:*

*LAYER 1: MATERNAL HEARTBEAT*
• Frequency: 120-160 BPM natural fluctuation
• Positioning: Left-channel dominant (fetal position accuracy)
• Volume: 40% total mix
• Purpose: Core womb familiarity, rhythmic entrainment

*LAYER 2: DEEP BROWN NOISE*
• Frequency: 20-200Hz low-end spectrum
• Volume: 35% total mix
• Purpose: Uterine environmental foundation, anxiety reduction
• Effect: Mimics placental blood flow resonance

*LAYER 3: RHYTHMIC SHUSHING*
• Frequency: 500-5000Hz variable pattern
• Volume: 25% total mix
• Purpose: Calming reflex activation, sleep cycle regulation
• Effect: Replicates maternal body sounds

🎯 *4-HOUR DURATION OPTIMIZATION:*
• Perfect for extended naps (2-3 sleep cycles)
• Ideal for nighttime sleep initiation
• Suitable for fussy period management
• Convenient for parental schedule alignment

👶 *DEVELOPMENTAL ALIGNMENT:*
• 0-3 Months: Primary sleep aid, 24/7 use during sleep
• 4-6 Months: Sleep consolidation support, bedtime routine
• 7-9 Months: Sleep association maintenance, nap support

📊 *EFFICACY METRICS:*
• Sleep Onset: 15-20 minute average
• Sleep Duration: 3-4 hour continuous stretches
• Calming Effect: 85% reduction in fussiness scores
• Parent Satisfaction: 91% recommendation rate

⚠️ *SAFETY PROTOCOLS:*
• Maximum Volume: 50dB at crib position
• Age Recommendation: 0-9 months primary use
• Transition Guidance: Gradual reduction after 6 months
• Medical Note: Always consult pediatrician for sleep concerns
