Producers are focused on improving the experience through the development of noise cancellation, but it’s essential to pay attention to specific technical aspects when selecting your next headphones.
Everywhere there is bustle… Over the years, the technology Headphone technology has progressed to counteract external sounds. It may sound like magic, but in reality it is something as simple as it is complicated to understand. Did you know that there are three different varieties of noise cancellation? Pay attention to what you are about to read, as it is always beneficial to have this information clear when purchasing gadgets of higher quality.
Noise cancellation is the ability of a device to reduce or eliminate surrounding noise, giving the user a clearer listening experience. Let’s say this is the most basic information. For the rest, we share the explanation made by JBLthe speaker and headphone manufacturer, which has been working with this technology in devices such as JBL Tune Flex, JBL Quantum 800 and JBL Quantum One.
Active noise cancellation technology works with the device emitting sound waves that are opposite or “negative” to ambient noise, effectively canceling noise. This is done through a microphone present in devices that have this technology, which works as a detector of outside noise and analyzes it in real time. Then, it switches to the emission of “anti-noise” sound waves that completely cancel ambient noise.
Advantages and disadvantages:
- One of its greatest advantages is that headphones with active noise cancellation technology help reduce users’ stress as they completely isolate them from the environment, improving attention levels allowing greater concentration.
- However, activating noise cancellation while using the headphones costs the battery.
- Total cancellation of environmental noise will depend on the amplitude of frequency responses that the headphones have. Given a wider frequency response, this will help cancel out a wider range of noise frequencies.
Unlike active noise cancellation, which uses microphones and sound waves to eliminate unwanted sounds, passive noise cancellation relies on the physical isolation of the ear canal. It does this by creating a barrier between the ear and external noise, thus preventing it from entering the ear.
This technology, instead of actively canceling noise from the environment, isolates it through the use of specialized ear tips: the tips use or do not use pads, and vary in size, shape and material, allowing more or less noise to enter the ear.
Advantages and disadvantages:
- Passive noise cancellation isolates low frequency sounds. That is, if the sound in the environment is of a higher frequency, it may still be heard.
- They are ideal for those environments that are not so noisy.
- They do not waste battery like active noise cancellation technology, which makes it longer lasting.
The adaptive noise cancellation technology is the newest yet. Unlike passive noise cancellation which relies on physical isolation, adaptive noise cancellation continually monitors surrounding sounds through built-in microphones and generates reverse or “anti-noise” sound signals to counteract and cancel out unwanted noise. desired.
The adaptive noise cancellation process automatically adjusts to changing environmental conditions, making it “adaptive.” In this way, it provides a quieter and clearer listening experience in noisy environments in a personalized way.
Advantages and disadvantages:
- Benefiting the listener, this technology gives adaptive noise canceling headphones the ability to be customizable.
