Slip-Stream Memory Fields in Historic Performance Spaces: A Case Study of the Sunderland Empire Theatre

Historic theatres frequently host reports of presence, atmosphere, and perceptual anomalies.
This paper introduces the concept of Slip-Stream Memory Fields — emergent perceptual zones created through the interaction of architectural form, acoustic focusing, collective emotional synchrony, and cultural-historical layering. Through a detailed case study of the Sunderland Empire Theatre, the analysis reframes haunting-like experiences as environmentally and culturally mediated perceptual intensifications rather than paranormal events.

The dataset and accompanying documentation present the laboratory framework used to test these phenomena empirically, integrating acoustic, environmental, and physiological measurements. Modules N–U include:
• Physiological correlation protocols and instrumentation (Module N)
• Data-analysis and pattern-recognition workflow (O)
• Cross-site replication protocol (P)
• Temporal-stability and longitudinal tracking (Q)
• Cross-disciplinary synthesis (R)
• Applied design and field-engineering guidelines (S)
• Dissemination and public-engagement framework (T)
• Meta-archive specification and unified dataset (U)

All materials are consolidated in Slipstream_SunderlandEmpire_v1.0.zip, containing the master paper, laboratory packs, supplementary surveys, calibration certificates, participant and ethics documentation, and a cleaned anisotropy CSV dataset describing the low-frequency directional field mapping within the theatre.

This release forms the public-safe segment of the wider Emotive Slip-Stream Project, demonstrating a reproducible, data-driven approach to the study of environmental perception in heritage architecture. No agency or paranormal attribution is implied; findings describe measurable interactions between architectural resonance, environmental gradients, and human physiological response.
