Why Do Neon Signs Buzz? Causes and Solutions
Neon signs have long been a staple in the world of advertising and decor, renowned for their vibrant colors and eye-catching glow. Originating in the early 20th century, these signs are created by bending glass tubes into various shapes and letters, which are then filled with noble gasses such as neon or argon. When an electrical current passes through the gas, it emits light, producing the familiar glowing effect. Neon signs are not just limited to businesses; they are also popular in homes, art installations, and even at events where their nostalgic and artistic appeal can transform any space into a lively environment. Companies like Reels Custom offer a wide range of custom neon signs that can be tailored to individual preferences, providing options that cater to both commercial and personal needs. Whether it's a classic "Open" sign for a store or a personalized neon art piece, these glowing lights continue to be a timeless and versatile form of expression.
How Neon Signs Work
Why Do Neon Signs Buzz: The Science Behind Neon Lights
Neon signs operate through a fascinating process that involves noble gasses and electrical currents. When high-voltage electricity is applied to neon gas enclosed within glass tubes, it excites the gas particles, causing them to glow brightly. This reaction creates the iconic vivid colors of neon signs. However, the buzzing sound often associated with neon lights is a byproduct of this process. The electrical current moving through the gas can create a slight vibration in the gas particles and the components of the sign, resulting in a faint but noticeable buzzing noise. This sound is particularly prominent when the sign is large or when the electrical current fluctuates, causing more pronounced vibrations.
The Components of Neon Signs That Cause Buzzing
The buzzing sound from neon signs can also be traced back to their internal components. Key elements that contribute to the buzzing include the transformers and electrodes. Transformers are used to step up the voltage required to ionize the gas inside the tubes. When the electrical current is converted by the transformer, it can generate an electromagnetic field that produces a humming or buzzing noise. Additionally, the electrodes at each end of the neon tube are responsible for initiating and sustaining the electrical discharge that lights the sign. The interaction between the electrical current and the gas can cause the electrodes to vibrate subtly, further contributing to the overall buzzing sound. Over time, the wear and tear on these components can make the buzzing more audible, especially if the sign has not been properly maintained.

Common Reasons Why Neon Signs Buzz
Why Do Neon Signs Buzz: Electrical Issues
One of the most common reasons for a buzzing neon sign is electrical issues. Fluctuations in the electrical current, poor wiring, or loose connections can cause irregularities in the flow of electricity, leading to vibrations that produce buzzing sounds. Electrical interference from other devices or a non-stable power supply can also exacerbate this issue. For instance, if the voltage supplied to the sign fluctuates frequently, the gas inside the neon tubes may react inconsistently, causing a pronounced buzz. Ensuring that the wiring is secure and that the electrical supply is stable can help minimize these unwanted noises. Regular checks and maintenance by a professional can identify and correct electrical issues before they become more significant problems.
Why Do Neon Signs Buzz: Transformer Problems
Transformers are crucial to the functioning of neon signs, as they provide the high voltage necessary for the neon gas to illuminate. However, problems with the transformer can often lead to buzzing noises. Over time, transformers can wear out or become damaged, which may cause them to produce a humming or buzzing sound. A malfunctioning transformer might struggle to maintain the correct voltage, leading to an inconsistent electrical current that increases buzzing. Additionally, if the transformer is not properly insulated or if it is mounted too close to other components, the vibrations it produces can be amplified. In some cases, replacing the transformer with a new, quieter model can significantly reduce the buzzing.
Why Do Neon Signs Buzz: Aging and Wear of Neon Tubes
Neon signs, like any other electrical appliance, are subject to aging and wear over time. As neon tubes age, the gas inside can begin to degrade, and the electrodes can wear down, both of which can contribute to increased buzzing. The glass tubes may also develop micro-cracks or become less stable, which can amplify the sound of the electrical discharge within. Furthermore, the rubber or silicone insulation that dampens the noise may deteriorate, allowing the buzzing sound to become more pronounced. Regular maintenance, including cleaning and checking the condition of the neon tubes and electrodes, can help extend the life of the sign and keep buzzing to a minimum. Replacing old neon tubes with new ones can also help mitigate noise issues, ensuring the sign operates smoothly and quietly.
Is the Buzzing of Neon Signs Harmful?
Why Do Neon Signs Buzz: Potential Health Concerns
While the buzzing sound from neon signs is often considered a minor annoyance, it's essential to explore whether this noise can pose any health concerns.
