When it comes to telephony and audio equipment, there are many technical terms that often leave us scratching our heads. One such term is sidetone – a feature that is ubiquitous in many devices, yet its purpose remains shrouded in mystery. In this article, we’ll delve into the world of sidetone, exploring its history, functionality, and most importantly, its point.
The Origins of Sidetone
Sidetone, also known as sidetone feedback or sidetone monitoring, has its roots in the early days of telephony. In the late 19th century, Alexander Graham Bell’s pioneering work on the telephone revolutionized communication. However, one of the earliest challenges faced by telephone users was the lack of feedback about their own voice. Without any auditory cue, speakers had no way of knowing how loud or soft they were speaking, leading to miscommunications and awkward pauses.
To address this issue, telephone manufacturers introduced sidetone – a subtle, real-time feedback of the speaker’s own voice. This innovation allowed speakers to adjust their voice levels and cadence, making conversations more natural and effortless.
What is Sidetone, and How Does it Work?
Sidetone is a clever engineering trick that adds a faint echo of the speaker’s voice back into their own earpiece or headphones. This echo, also known as “voice feedback,” allows the speaker to hear their own voice, albeit very softly, in real-time. The sidetone signal is typically generated by the microphone or transmitter, and then fed back into the audio circuitry.
The sidetone mechanism works on the principle of acoustic feedback. When we speak into a microphone, our voice is converted into an electrical signal, which is then transmitted to the receiving end. Sidetone takes a small portion of this electrical signal and sends it back to the speaker, creating a subtle, delayed echo of their own voice. This feedback loop helps the speaker adjust their vocal output, ensuring that their voice is projected at the optimal level.
Sidetone in Modern Devices
Today, sidetone is an integral feature in many audio devices, including:
- Telephones (wired and wireless)
- Headphones (wired and wireless)
- Microphones (USB, condenser, and dynamic)
- Hearing aids
- Audio conferencing equipment
- Gaming headsets
Sidetone in Everyday Life
Sidetone may seem like a minor feature, but its impact is profound. Without sidetone, we’d struggle to communicate effectively, especially in noisy environments or over long distances.
Imagine making a phone call without hearing your own voice – you’d have no idea if you’re being too loud or too soft. You might end up shouting into the phone, only to bewilder the person on the other end. Or, worse still, you might be speaking too softly, making it difficult for the listener to understand you.
Sidetone ensures that we’re always aware of our voice levels, allowing us to:
- Adjust our tone and pitch
- Maintain an optimal speaking volume
- Engage in smoother conversations
- Avoid misunderstandings
The Psychological Aspect of Sidetone

What is Sidetone and how does it work?
Sidetone is a faint, audible echo of one’s own voice that is feedback into the headphone or earpiece of a communication device, such as a walkie-talkie or telephone. This allows the speaker to hear their own voice in real-time, which can be helpful in various communication scenarios. Sidetone is typically generated by redirecting a small portion of the speaker’s audio signal back into their own earpiece.
The purpose of sidetone is to provide the speaker with auditory feedback, allowing them to monitor the volume and quality of their own voice. This can be particularly useful in situations where the speaker needs to adjust their voice to be heard clearly, such as in noisy environments or when speaking over long distances. Sidetone can also help speakers adjust their tone and pitch to convey emotions and emphasis more effectively.
Is Sidetone the same as Echo Cancellation?
No, sidetone and echo cancellation are not the same thing. Echo cancellation is a technology used to remove echoes and reverberations from audio signals, typically in real-time communication systems like teleconferencing or VoIP calls. Echo cancellation helps to eliminate distracting echoes and improve the overall audio quality. In contrast, sidetone is a deliberate feedback of the speaker’s own voice, intended to provide auditory feedback and assist with communication.
While both technologies deal with audio signals, their purposes and functions are distinct. Sidetone is focused on providing the speaker with a sense of their own voice, whereas echo cancellation is focused on removing unwanted echoes and improving audio clarity. In some cases, sidetone and echo cancellation may work together to enhance the overall communication experience, but they are separate technologies with different goals.
Why do some people find Sidetone distracting?
Some people may find sidetone distracting because it can be unsettling to hear their own voice in their ear while speaking. This can be particularly true in situations where the speaker is not accustomed to hearing their own voice in real-time. The faint echo of their own voice can be distracting and may cause them to adjust their speaking pattern or volume unnecessarily. Additionally, some individuals may find sidetone annoying or even embarrassing, especially if they are self-conscious about their voice.
It’s worth noting that sidetone is a subjective experience, and people’s reactions to it can vary greatly. Some people may not find sidetone distracting at all, and may even find it helpful in their communication. It’s also possible to adjust the volume or tone of sidetone to make it less noticeable or more comfortable for the speaker.
Can Sidetone be turned off or adjusted?
Yes, in many cases, sidetone can be turned off or adjusted to suit the speaker’s preferences. The ability to adjust or disable sidetone typically depends on the specific communication device or system being used. Some devices may have a dedicated sidetone control or option, while others may require manual adjustments to the audio settings.
It’s also worth noting that some communication systems, such as certain types of radios or intercoms, may not allow sidetone to be turned off or adjusted. In these cases, sidetone may be an inherent feature of the system and cannot be changed.
