When it comes to studio monitors, silence is golden. A slight hiss or hum can be distracting, ruining the overall listening experience and making it difficult to focus on your work. Active monitors, in particular, have gained a reputation for being prone to hiss. But is this reputation justified? In this article, we’ll delve into the world of active monitors and explore the reasons behind the hiss. We’ll also examine the circumstances under which hiss is more likely to occur and provide tips on how to minimize it.
What Causes Hiss in Active Monitors?
Hiss in active monitors can be attributed to several factors. Electrical noise is a common culprit, and it can stem from various sources:
Electromagnetic Interference (EMI)
EMI occurs when other electronic devices in the vicinity of your active monitors generate electromagnetic fields that interfere with the monitor’s operation. This can cause a hissing or buzzing sound. Common EMI culprits include computers, televisions, and fluorescent lighting.
Radio-Frequency Interference (RFI)
RFI is similar to EMI but is specific to radio frequencies. This can include signals from radio stations, cell phones, and other wireless devices.
Power Supply Noise
The power supply unit (PSU) in your active monitor can also generate noise, which can manifest as hiss. This is often due to the PSU’s internal components, such as the transformer or voltage regulator.
Analog-to-Digital Conversion (ADC) Noise
The ADC process can introduce noise into the signal path, resulting in hiss. This is particularly true for lower-quality converters or those operating at higher sampling rates.
Poor Shielding and Grounding
Inadequate shielding and grounding of the monitor’s internal components can allow electrical noise to seep into the signal path, causing hiss.
When Are Active Monitors More Likely to Hiss?
While hiss can occur in any active monitor, certain circumstances increase the likelihood of its appearance:
Low-Gain Inputs
When using low-gain inputs, such as those found on some audio interfaces or mixers, the monitor’s gain stage may need to be turned up to compensate. This can amplify any existing noise, making hiss more prominent.
High-Sensitivity Drivers
Active monitors with high-sensitivity drivers may be more prone to hiss due to their ability to pick up even the faintest electrical signals.
Improper Room Acoustics
A room with poor acoustics can exacerbate hiss, making it more noticeable to the listener. This includes rooms with reflective surfaces, minimal sound absorption, and inadequate diffusers.
How to Minimize Hiss in Active Monitors
While it’s impossible to completely eliminate hiss, there are steps you can take to minimize its presence:
Use High-Quality Cables and Connectors
Invest in high-quality cables and connectors to reduce the likelihood of electrical noise entering the signal path.
Optimize Your Studio Layout
Position your active monitors and other equipment to minimize electromagnetic interference. Keep them away from computers, televisions, and other potential noise sources.
Use a High-Quality Power Supply
Choose a power supply unit that is designed to minimize electrical noise and interference.
Adjust the Monitor’s Gain Stage
Optimize the gain stage of your active monitor to find the sweet spot where hiss is minimized without sacrificing overall volume.
Invest in Noise-Reducing Technologies
Some active monitors feature noise-reducing technologies, such as noise-sensing circuits or proprietary hiss-reduction algorithms.
Maintain Your Studio
Regularly clean and maintain your studio equipment to ensure that dust, dirt, and other contaminants don’t contribute to hiss.

As we’ve seen, hiss in active monitors is a complex issue with multiple causes. By understanding the factors that contribute to hiss and taking steps to minimize it, you can create a more enjoyable and productive listening experience. Remember, a well-designed and well-maintained active monitor can provide accurate, detailed sound with minimal hiss.
Conclusion
The age-old question “Do active monitors hiss?” has a nuanced answer. While hiss can occur in any active monitor, it’s not an inherent trait. By being aware of the causes of hiss and taking steps to minimize it, you can unlock the full potential of your active monitors and enjoy a more immersive listening experience. So, the next time you’re tempted to ask “Do active monitors hiss?”, you’ll know the silent truth: it’s not the monitors, it’s the circumstances.
What is monitor hiss and why does it occur?
Monitor hiss is a high-pitched noise that emits from active monitors, particularly when they are turned on but not playing any audio. This phenomenon occurs due to the electrical current flowing through the speakers, even when they are not reproducing sound. The hiss is often more noticeable in quiet environments and can be distracting for artists, producers, and engineers who rely on accurate sound reproduction.
The hiss is typically a result of the amplifier’s circuitry and the speaker’s design. When an active monitor is turned on, the amplifier is always “on” and ready to receive an audio signal, even if no sound is being played. This ” idle” state can cause a faint humming or hissing noise, which can be more pronounced in certain monitors.
Do all active monitors hiss?
Not all active monitors hiss, but many do to some extent. The level of hiss can vary greatly between different models and brands. Some high-end active monitors are designed with noise reduction features that minimize or eliminate hiss, while budget-friendly options might be more prone to hissing. Additionally, some monitors may have a greater tendency to hiss due to their design or component quality.
It’s also worth noting that some monitors might exhibit hiss only under certain conditions, such as when the volume is turned up or when a specific type of audio is being played. In some cases, the hiss might be imperceptible to the human ear, while in others, it can be annoyingly loud.
Is monitor hiss a sign of poor quality?
Monitor hiss does not necessarily indicate poor quality. While it’s true that some low-end active monitors might be more prone to hissing, many high-end models can also exhibit this trait. The presence of hiss is more often a result of the amplifier’s design and the speaker’s components rather than a reflection of the monitor’s overall quality.
In fact, some high-end active monitors might hiss due to their high sensitivity and ability to pick up subtle sounds. However, a well-designed monitor should be capable of producing accurate and clear sound, hiss or not. If you’re concerned about hiss, look for monitors with noise reduction features or those specifically designed to minimize electrical noise.
Can monitor hiss be eliminated?
While it’s challenging to completely eliminate monitor hiss, there are steps you can take to reduce or minimize it. One approach is to invest in high-quality active monitors with built-in noise reduction features, such as noise cancellation or electrical noise filtering. These features can help to reduce hiss to almost imperceptible levels.
Additionally, proper gain staging and volume management can also help to reduce hiss. By keeping the volume at reasonable levels and adjusting the gain accordingly, you can minimize the likelihood of hiss. Furthermore, placing the monitors in a well-insulated room or using acoustic treatment can also help to reduce ambient noise and make the hiss less noticeable.
How can I reduce monitor hiss in my studio?
There are several ways to reduce monitor hiss in your studio. Firstly, consider investing in high-quality active monitors with noise reduction features. You can also experiment with different speaker placements, angles, and distances to find the sweet spot that minimizes hiss. Proper cable management and using high-quality cables can also help to reduce electrical noise.
Another approach is to use acoustic treatment in your studio, such as absorption panels or diffusion panels, to reduce ambient noise and reverberation. This can help to create a more controlled acoustic environment, making the hiss less noticeable. Finally, consider using a noise reduction plugin or software during mixing and mastering to help identify and eliminate unwanted frequencies.
Is monitor hiss a problem for music production?
Monitor hiss can be a problem for music production, particularly in situations where accurate sound reproduction is crucial.
