Vegas Residency Vocal Load & Recovery Planner

Vegas Residency Phonation Lab • Bio-Acoustic Engine

Clinical Directive: “We All Need To Sit Down and Shut Up” — B. Manilow (Vegas Health Pause)

Biomechanical Inputs

Setlist Duration (Minutes) 85 min

Direct active phonation duration under theatrical pressure.

Belt / High Tessitura Load 42%

Proportion of sustained high subglottic pressure & high collision velocity.

Desert Stage / Room Humidity 18% RH

Sub-25% RH accelerates vocal fold lamina propria dehydration by 3.4x.

Stage In-Ear / Ambient SPL 94 dBA

Lombard reflex: elevated background noise forces higher phonatory contact pressure.

Mandatory Silence (Off-Show Hrs) 5.5 hrs

Strict complete silence ("Sit Down & Shut Up") allowing mucosal edema clearance.

Vocal Tract Stamina Tier

Prior pathology or vocal fold thinning requires wider recovery windows.

Standard Weekly Show Run

Quickly apply default template to the 4-week matrix below.

Weekly Vocal Dose (D_v) ELEVATED

184.2 km / wk

Total tissue displacement equivalent: ~4.4 marathons of vocal fold collision.

Phonation Load Index MANAGEABLE

74 / 100

Subglottic stress index based on 42% belt load.

Hydration Deficit Factor DRY RISK

1.82 x multiplier

Desert 18% RH requires 35min isotonic nebulization daily.

Cumulative Cancellation Risk MODERATE

28% 30-day peak

Predicted acute laryngitis / edema threshold.

Visualizes daily accumulation vs recovery clearance. Spikes into red zone signal acute vocal shutdown.
