Battersea & Modern Venue Acoustic Science
Like the Apple Music Hall beneath London’s Battersea Power Station, modern hybrid venues demand dual capability: intimate, pristine acoustic clarity for live ticketed audiences combined with controlled reverberation for multi-track broadcast recordings.
How Critical Distance (r_c) Dictates Sound Quality
Critical distance is the radius from a stage sound source where the direct sound pressure equals the reflected reverberant field pressure. Inside r_c, listeners hear crisp articulation; beyond r_c, reverberant reflections dominate.
Bass Ratio (BR) & Warmth Formulation
Bass Ratio is calculated as [RT60(125Hz) + RT60(250Hz)] / [RT60(500Hz) + RT60(1000Hz)]. A ratio between 1.10 and 1.35 delivers warmth and punch without muddy low-frequency resonance.
Calculations & Material Absorption Coefficients
This model integrates Sabine and Norris-Eyring boundary equations. Material absorption coefficients (α) are calibrated across standard 1/1 octave bands (125 Hz to 4 kHz) incorporating audience air attenuation.
Standing Wave Eigenmodes (Room Modes)
Axial room modes occur along length, width, and height axes: f = (c/2) × √[(p/L)² + (q/W)² + (r/H)²]. The modal tab displays resonant standing wave frequencies to verify smooth modal spacing.
Web Audio Convolution Audition
The audition engine synthesizes an algorithmic impulse response tailored dynamically to the exact Sabine decay envelope and early reflection delay of your modeled room.
