How do spirit boxes work?

If you’re a ghost hunter or simply intrigued by the paranormal, you may have come across these devices in your quest to communicate with spirits. A spirit box, also known as a ghost box, is an electronic device that scans through radio frequencies rapidly, allowing spirits to manipulate the audio and communicate. This article will dive into the mechanics behind these devices and explain how they are believed to facilitate communication between the living and the dead. Whether you’re a seasoned ghost hunter or just getting started, understanding how spirit boxes work may enhance your next supernatural encounter.

How Do Spirit Boxes Work


If you’ve ever had an interest in the paranormal or have wanted to connect with spirits, you may have come across a device known as a spirit box. Spirit boxes are often used in ghost hunting and are believed to facilitate communication with the spirit world. In this article, we’ll explore what spirit boxes are, how they work, their potential benefits and limitations, as well as provide some tips for using them safely.

What is a Spirit Box?


A spirit box is a device used in paranormal investigations to communicate with spirits. It is essentially a modified radio scanner that rapidly scans through radio frequencies, creating a white noise effect. This white noise is believed to provide a medium through which spirits can communicate.


The main purpose of a spirit box is to detect and facilitate real-time communication with spirits. By sweeping through radio frequencies, the device allows for potential interactions with spirits through electronic voice phenomena (EVP). It provides a unique tool for ghost hunters to connect with the spirit world and gather evidence of paranormal activity.

The Components of a Spirit Box

Radio Scanner

At the core of a spirit box is a radio scanner. This scanner typically has the ability to tune into various frequencies, such as AM and FM radio stations. The rapid scanning feature is what distinguishes a spirit box from a regular radio scanner, as it allows for a continuous sweep through the frequencies.

Noise Suppression

To enhance communication with spirits, most spirit boxes are equipped with noise suppression technology. This helps reduce external interference or background noise, ensuring that any responses or EVPs captured are as clear as possible.

Audio Output

Spirit boxes generally provide an audio output, either through built-in speakers or by connecting headphones or external speakers. This allows users to hear any potential responses from spirits in real-time and analyze the captured EVPs.

How Does a Spirit Box Work?

Sweeping Radio Frequencies

When a spirit box is turned on, it rapidly scans through a range of radio frequencies. This sweeping motion allows for a continuous flow of audio, creating a white noise effect. The idea behind this technique is that spirits can manipulate this white noise to communicate with the living.

White Noise and EVP Communication

White noise is known to act as a form of audio “blank canvas” that spirits can utilize to communicate. It is believed that spirits can manipulate the frequencies within the white noise to form words or phrases, resulting in EVPs being captured by the spirit box. These EVPs are then played back through the device’s audio output.

Real-Time Communication with Spirits

One of the unique aspects of spirit boxes is their ability to facilitate real-time communication with spirits. By scanning through radio frequencies at a rapid pace, the chances of capturing real-time responses from spirits increase. Users can pose questions or prompts and listen for any potential responses that may be relayed through the white noise.

Using a Spirit Box for Ghost Hunting

Connecting with Spirits

Spirit boxes are commonly used by ghost hunters to establish a connection with spirits. By using a spirit box during investigations or in haunted locations, ghost hunters hope to engage in conversation or gather evidence of paranormal activity. The ability to communicate in real-time with spirits can provide a thrilling and immersive experience for ghost hunters.

Understanding and Interpreting Responses

When using a spirit box, it is essential to have a framework for understanding and interpreting responses from spirits. This requires careful listening and analysis of the captured EVPs. Some responses may be clear and direct, while others may be more subtle or require interpretation. Ghost hunters often develop their own techniques for understanding the messages conveyed by spirits through the spirit box.

Recording and Analyzing EVPs

To capture and document potential evidence of spirit communication, it is recommended to record audio while using a spirit box. This allows for a more thorough analysis of the EVPs captured. Ghost hunters can listen back to recordings and analyze the responses in greater detail, potentially uncovering hidden messages or further validating their experiences.

Types of Spirit Boxes

Traditional Spirit Boxes

Traditional spirit boxes are standalone devices specifically designed for spirit communication. They often come with various features, such as frequency sweep options, noise suppression capabilities, and audio output options. Traditional spirit boxes are purpose-built for ghost hunting and are typically the preferred choice for serious investigators.

Ghost Box Apps

In recent years, there has been a rise in the popularity of ghost box apps for smartphones. These apps mimic the functionality of traditional spirit boxes, utilizing the device’s internal radio capabilities to create the necessary white noise. While they may not offer the same level of functionality as dedicated spirit boxes, ghost box apps provide a more accessible and portable option for spirit communication.

DIY Spirit Boxes

For those with a knack for electronics and tinkering, DIY spirit boxes offer an opportunity to personalize and customize their own devices. DIY spirit boxes can range from simple modifications of existing radio scanners to more advanced builds utilizing radios and specialized components. Building a DIY spirit box allows individuals to experiment and tailor the device to their specific needs and preferences.

Tips for Using a Spirit Box Safely

Create a Protective Environment

Before using a spirit box, it is recommended to create a protective environment. This can be done through prayer, meditation, or setting the intention to invite only positive and benevolent spirits. Creating a protective space can help minimize any negative or unwanted experiences during spirit box sessions.

Set Clear Intentions

Clearly state your purpose, whether it’s seeking answers, gathering evidence, or simply exploring the paranormal. This clarity of intention can help guide the conversation and interactions with spirits.

Establish Communication Guidelines

When using a spirit box in a group setting, it is essential to establish communication guidelines. This ensures that everyone involved understands the proper etiquette and respects boundaries during the session. Guidelines may include taking turns asking questions, speaking clearly, and avoiding disrespectful or provocative language.

Respectful and Ethical Use

Always approach spirit box sessions with respect and ethical considerations. Treat any potential spirit communication with kindness and compassion. It is important to remember that the spirits being communicated with were once living beings and deserve to be treated with dignity. Avoid using spirit boxes in locations where they may be disruptive or disrespectful, such as cemeteries or sacred sites.


Spirit boxes are fascinating devices that offer a unique way to connect with the spirit world and potentially gather evidence of paranormal activity. Whether you choose a traditional spirit box, a ghost box app, or decide to build your own, using these devices requires an open mind, careful analysis, and ethical considerations.
