Noise isolation is incredibly important to every music lover. There’s nothing more frustrating than being on a crowded bus or train and not being able to hear the audio properly.
That’s why in-ear TWS (True Wireless Stereo) speakers are very popular now. But the question remains – can in-ear TWS speakers really block out external noise effectively?
Yes, TWS speakers can block out external noise to some extent. The degree of noise isolation depends on the type of earbud, with some using passive noise isolation and others using active noise cancellation (ANC) technology.
ANC is generally more effective in reducing external noise, but passive noise isolation can still provide some level of noise reduction.
In this article, I’m going to examine the different types of noise isolation and test the effectiveness of in-ear TWS speakers in blocking out external noise.
Types of Noise Isolation
As someone who loves listening to music on the go, I’ve become quite familiar with the different types of noise isolation available in earbuds.
There are two types of noise cancellation methods:
Passive Noise Cancellation:
This method reduces external noise by physically blocking it. It is achieved through the use of sound-absorbing materials such as foam, rubber or silicone.
This method is effective in reducing low-frequency sounds such as engine noise, but it is not very effective for high-frequency sounds.
Active Noise Cancellation:
This method uses advanced digital signal processing (DSP) technology to cancel out external noise by generating a counter sound wave.
The sound wave is created by using an onboard microphone to sample external noise and then generating a signal that is the exact opposite of the sampled noise. This method is effective for both low-frequency and high-frequency sounds.
Passive Noise Isolation
Passive noise isolation refers to the physical blocking of sound waves from entering the ear canal.
How In-ear TWS Speakers Achieve Passive Noise Isolation
This is achieved by using ear tips that fit snugly into the ear and create a seal. In-ear TWS speakers typically come with multiple sizes of ear tips. They allow the user to choose the size that fits their ear canal best.
I decided to test the passive noise isolation of my in-ear TWS speakers by wearing them in a noisy environment. I went to a coffee shop during peak hours and played music at a comfortable volume.
The coffee shop was fairly loud, with multiple conversations happening at once, the sound of the coffee machine, and background music playing. I found that with the in-ear TWS speakers in my ears and the music playing, the external noise was greatly reduced.
I could still hear some of the background noise, but it was much quieter than without the speakers.
It’s important to note that the effectiveness of passive noise isolation is dependent on the seal created by the ear tips. If the ear tips don’t fit well, then the sound waves can still enter the ear canal and reduce the effectiveness of noise isolation. I tried different sizes of ear tips and found that a tight seal was crucial for effective noise isolation.
Advantages and limitations of passive noise isolation
Advantages of passive noise isolation include the simplicity of the technology and the lack of need for a power source.
However, passive noise isolation has limitations in terms of the amount of external noise it can block out.
Active Noise Cancellation
Active noise cancellation (ANC) is a more advanced form of noise isolation.
How In-Ear TWS Speakers Achieve active Noise Cancellation
ANC uses microphones to detect external noise and creates an opposing sound wave that cancels out the external noise. This creates a quieter listening experience, even in environments with high levels of external noise.
In-ear TWS speakers with ANC are typically more expensive than those without, but they offer a more immersive and isolated listening experience. I decided to test the ANC of my in-ear TWS speakers by wearing them in a noisy environment and turning on the ANC feature.
I went to a busy street corner during rush hour and played music at a comfortable volume. With the ANC turned on, the external noise was greatly reduced. I could still hear some of the traffic noise, but it was much quieter than without the ANC feature turned on.
One thing to keep in mind is that ANC works best with low-frequency sounds, such as the hum of an airplane engine. It’s not as effective with higher-frequency sounds, such as human voices. However, in my testing, I found that ANC was still effective in reducing the overall volume of external noise.
Advantages and Limitations of Active Noise Cancellation
Advantages of ANC include the ability to cancel out external noise effectively and the ability to switch the feature on and off as needed. However, ANC requires a power source, which means that the battery life of the in-ear TWS speakers may be shorter when the ANC feature is turned on.
Testing the Effectiveness of In-ear TWS Speakers in Blocking Out External Noise
To test the effectiveness of my in-ear TWS speakers in blocking out external noise, I conducted a series of tests in different environments. I used the same playlist of music for each test and played it at a comfortable volume.
The Testing Environment and Equipment Used
One of the environments I tested was a busy city street corner during rush hour. Without any noise isolation features turned on, the external noise was very loud and made it difficult to hear the music clearly.
Presentation of the Result
With passive noise isolation, the external noise was greatly reduced, but I could still hear some of the traffic noise. With ANC turned on, the external noise was almost completely eliminated, creating a much more immersive listening experience.
Another environment I tested was a crowded coffee shop during peak hours. Without any noise isolation features turned on, the external noise was loud. And its difficult to hear the music clearly.
With passive noise isolation, the external noise was greatly reduced, but I could still hear some of the background noise. With ANC turned on, the background noise was greatly reduced, creating a more enjoyable listening experience.
In both tests, I found that ANC was more effective than passive noise isolation in reducing external noise. However, passive noise isolation was still effective in reducing external noise, especially in environments with lower levels of noise.
