Paranormal Investigation: How Professionals Actually Do It (Step by Step)

A paranormal investigator is a person who uses documented, systematic methodology to examine reported phenomena that fall outside conventional scientific explanation. "Paranormal" means "beyond normal": phenomena that the current scientific framework cannot yet account for. It does not mean that ghosts or entities have been confirmed.

Paranormal investigation is not:

• TV ghost hunting, where the aim is dramatic footage
• spiritual remediation, exorcism or rituals
• debunking by default (the method requires real openness to whatever the evidence shows)
• content creation first. Documentation comes first, and content, if any, follows from it.

The Indian Paranormal Society, where Rith is a core team member, states the same boundary: "We do not claim to exorcise or eliminate paranormal entities. Our role is to investigate, document, and support individuals through education and awareness."

Rule zero: "Every investigation starts with one rule — prove it isn't paranormal first. If you can't eliminate the natural explanation, you don't have a case." (Rith Deb)

Stage 1: Case intake and pre-investigation research

Before anyone visits, take a detailed account from the person reporting:

• when the phenomena started, and what exactly happens
• how many people have experienced it, and whether they experience the same thing
• recent changes to the location (renovation, new appliances, new occupants)
• health changes in the household, such as headaches, fatigue or nausea. Several environmental causes (CO, mould, some EMF conditions) also have health effects.
• pet behaviour, which can be an early warning sign of CO

Then research the site: historical records, eyewitness accounts and a structural survey. Understanding the space on paper comes first.

Stage 2: Environmental baseline

An environmental baseline is the set of readings that describes a location's normal conditions before the investigation begins. Without it, every later reading is contaminated, because you cannot tell an anomaly from the building's ordinary behaviour.

Document across all accessible areas:

• EMF in every room, with every electrical source identified and mapped
• Temperature mapping
• Air quality, including carbon monoxide in residential cases
• Acoustics and infrasound
• Structural conditions and known interference sources

This step usually takes the first hour on site. It produces no dramatic footage, which is exactly why entertainment content skips it.

Stage 3: Controlled evidence capture

Capture audio, video, photographs and instrument data under controlled conditions:

• Fixed positions, not waving. Place meters at fixed measurement points. A meter waved through the air records every wiring run and appliance in the building, which is noise.
• At least two meters per fixed point. One meter cannot separate a real localised anomaly from instrument error. Two meters reading the same anomaly at the same time, from different angles, with no identified source, is data worth noting.
• Log everything with time, location and environmental context.
• Mark audio anomalies in-session with timestamps, so the review is targeted later.

Stage 4: Analysis against natural explanations

Every item is reviewed against the baseline and against known explanations:

• Compare an EMF spike with the baseline map.
• Compare an audio capture with the site's acoustic profile.
• Work through the natural-cause checklist: structural, acoustic, electromagnetic, psychological and human error.

What counts as an EMF anomaly: a reading elevated beyond the established baseline, in a spot with no known electromagnetic source, that repeats across multiple measurements. The number alone means nothing. What matters is the deviation from baseline.

Classifying EVP: EVP captures are commonly graded Class A, B or C. Class A is clearly intelligible without enhancement, agreed on by multiple listeners, and needs no processing. Never inflate a Class C capture into something it isn't.

Stage 5: The written report

Documentation is the core product of a paranormal investigation. Every case produces a written report covering what was reported, what was investigated, what was found, what was explained, and what remains unexplained. Inconclusive evidence is labelled inconclusive. Use the free template below.

The Indian Paranormal Society describes its own process in six stages: initial contact and briefing, pre-investigation assessment, on-site investigation, evidence analysis, client consultation, and follow-up support. It is the same logic, with the client debrief and aftercare split out as their own stages (IPS Investigations).

Equipment documents conditions. It does not detect spirits.

Avoid cheap novelty "ghost detector" meters. They are not calibrated for anything in particular and react to phones, bodies and passing cars.

On your phone: Rith's free Android app ECHOVOX calibrates its EMF meter against the location's ambient baseline. It records EVP with in-session anomaly timestamps and captures up to 48 kHz, and its spirit box has a controllable sweep for reproducible sessions. Its Direct Voice Q&A feature is labelled exploratory, not evidentiary. How ECHOVOX works

Reading EMF numbers (typical indoor ranges, from Rith's field guide):

• 0.5–2.5 mG: normal background with ordinary wiring. Means nothing.
• 2–10 mG within half a metre of appliances: still normal.
• 5–20 mG or more near old wiring, junction boxes or breaker panels: elevated, but with an identified source.

Carbon monoxide

Carbon monoxide (CO) is a colourless, odourless gas whose low-level symptoms closely mirror "haunted house" reports. Those symptoms include headaches, dizziness, visual disturbances at the edge of vision, sounds that are hard to locate, dread and a sense of presence. A widely cited case was documented by physician William Wilmer in the American Journal of Ophthalmology in 1921. A family's "haunting" turned out to be a faulty furnace, and the phenomena stopped once it was repaired.

CO readings to know:

• 0–9 ppm: normal
• 10–35 ppm: low-level chronic exposure
• 35–70 ppm: symptoms in healthy adults over hours
• 70+ ppm: dangerous

Safety rule: if a residential investigation finds CO above 10 ppm from an unidentified source, the investigation stops. The family opens up the building, calls a gas technician, and does not return until the source is repaired and re-tested. Read the CO guide

Infrasound

Infrasound is sound below 20 Hz, below the threshold of human hearing. Around 18–19 Hz it is associated with unease, a sense of presence, movement at the edge of vision and pressure in the chest. In 1998, Coventry University engineer Vic Tandy documented an 18.98 Hz standing wave produced by a fan in a laboratory where staff reported such experiences. When the fan was turned off, the experiences stopped. To test for it, use a condenser microphone with flat response below 20 Hz and spectrogram software, then switch mechanical systems off one by one. Read the infrasound guide

Electromagnetic fields

High-EMF spots near wiring, appliances and breaker panels produce spikes that untrained investigators mistake for activity. Some researchers also propose that high-EMF environments cause physical symptoms that people interpret as paranormal. Both hypotheses are unconfirmed, which is why the EMF meter is a documentation tool.

Acoustics, structure and psychology

Settling buildings, plumbing, drafts, sound travelling through shared walls, sleep states, stress and the team's own confirmation bias all need to be ruled out.

• Client welfare comes first. The people who call an investigator are frightened, so stay calm and professional, and refer them to a doctor or technician when health or safety is at stake.
• No rituals, no remedies, no "removal".
• Respect property, privacy and beliefs. IPS's values include respecting "both the client and the client's property".
• Honesty over drama. Never stage, exaggerate or sensationalise ambiguous evidence for content.
• Respect other groups. Cooperation, not rivalry, is part of IPS's stated values.
• Respect access rules. Government restrictions apply at some sites. For example, IPS notes that night-time access to Bhangarh Fort is restricted.

India adds a dense cultural layer. By the time an investigator arrives, a family has often already interpreted events through religious belief and folklore, and has sometimes paid for rituals. A competent investigator respects those beliefs and still gives an evidence-based assessment.

Indian homes also have specific natural-cause risks: LPG stoves in poorly ventilated kitchens, unserviced gas geysers, generators run in enclosed spaces during power cuts, and traditional chulhas, all of which are CO sources.

Examples from IPS case files. The Indian Paranormal Society publishes case files for well-known Indian locations, including Bhangarh Fort and Kuldhara Village (Rajasthan), Mukesh Mill (Mumbai), Tunnel 33 (Shimla) and Lambi Dehar Mines (Uttarakhand). Each lists the reported activity, IPS's findings and a status (IPS Case Files). They are worth reading to see how a team documents reported activity at heritage and industrial sites. Read IPS's findings in its own words.
