If you’re looking for headphones that can block out the noise from your surroundings and let you enjoy your music, podcasts, or audiobooks without distractions, you might want to consider headphones with good isolation.
Isolation is the ability of headphones to reduce the amount of ambient noise that reaches your ears, either passively or actively. In this article, we’ll explain what isolation is, why it matters, how we test it, and what are the best headphones for isolation in 2024.
What is Isolation and Why Does It Matter?
Isolation is a measure of how well headphones can prevent external noise from interfering with your listening experience. There are two types of isolation: passive and active.
Passive Noise Isolation vs. Active Noise Cancellation
Passive noise isolation is achieved by creating a physical barrier between your ears and the outside world. This can be done by using ear cups or earbuds that fit snugly around or inside your ears, blocking some of the sound waves from entering. Passive noise isolation depends on the design, materials, and fit of the headphones, and it usually works better for higher-frequency sounds than lower-frequency ones.
Active noise cancellation (ANC) is a technology that uses microphones to pick up ambient noise and generate an opposite sound wave that cancels it out. This can be done by using a built-in chipset or an external device that processes the sound signals and sends them to the speakers. Active noise cancellation requires power and electronics to work, and it usually works better for lower-frequency sounds than higher-frequency ones.
Some headphones combine both passive noise isolation and active noise cancellation to achieve the best results. However, active noise cancellation can also introduce some drawbacks, such as reduced sound quality, increased battery consumption, or added weight and cost.
Factors That Affect Isolation Performance
The performance of isolation depends on several factors, such as:
-
The type of headphones:
Over-ear headphones tend to have better passive noise isolation than on-ear or in-ear headphones because they cover more of your ears. However, some in-ear headphones can also have excellent passive noise isolation if they have a tight seal with your ear canal. Active noise cancellation can be found in any type of headphones, but it’s more common in over-ear or in-ear models.
-
The design of the headphones:
The shape, size, material, and padding of the ear cups or earbuds can affect how well they block out noise. For example, closed-back headphones usually have better passive noise isolation than open-back headphones because they prevent sound from leaking out or in. Similarly, earbuds can have different shapes and sizes, such as round, oval, conical, or flanged, to fit different ear shapes and sizes. The material and thickness of the padding can also affect how comfortable and isolating the headphones are.
-
The fit of the headphones:
The fit of the headphones is crucial for achieving good isolation. If the headphones are too loose or too tight, they can let in more noise or cause discomfort. The fit can be adjusted by using different sizes of ear tips, ear hooks, headbands, or clamps. The fit can also vary depending on the shape and size of your ears, head, and hair.
-
The environment:
The environment can also affect how well the headphones isolate noise. For example, if you’re in a quiet place, you might not need much isolation to enjoy your audio. However, if you’re in a noisy place, such as a busy street, a train station, or an airplane, you might need more isolation to block out the noise. The type and level of noise can also matter. For example, some headphones might be better at isolating constant noises, such as engine hums or fans, than intermittent noises, such as voices or sirens.
How We Test Isolation of Headphones
At our technology news outlet, we have a rigorous and reliable method for testing the isolation of headphones. We use a combination of objective measurements and subjective evaluations to assess how well the headphones reduce ambient noise.
Our Testing Procedure
Our testing procedure consists of the following steps:
- We use a dummy head with microphones in its ears to simulate a human listener. We place the headphones on the dummy head and adjust them to ensure a proper fit.
- We use a sound level meter to measure the sound pressure level (SPL) in decibels (dB) of the ambient noise in our testing room. We use a pink noise generator to produce a uniform noise spectrum that covers all audible frequencies.
- We use an audio interface and a computer to record the sound that reaches the microphones in the dummy head’s ears. We record two samples: one with the headphones turned off (or without ANC) and one with the headphones turned on (or with ANC).
- We use an audio analysis software to compare the two samples and calculate the difference in SPL between them. This difference represents how much noise the headphones isolate in dB.
- We repeat this process for different frequency bands: low (20-250 Hz), mid (250-2000 Hz), high (2000-20000 Hz), and overall (20-20000 Hz). This allows us to evaluate how well the headphones isolate different types of noises.
- We also test the isolation performance of the headphones in different scenarios: office, commute, and flight. We use recordings of real-world noises that match these scenarios and play them through speakers around the dummy head. We measure and compare the SPLs as before.
Isolation Score and Tests
Based on our measurements, we assign an isolation score to each pair of headphones we test. The isolation score is a number between 0 and 10 that reflects how well the headphones isolate noise across all frequency bands and scenarios. The higher the score, the better the isolation.
The amount of noise reduction (in dB) the headphones achieve in comparison to neither headphones nor ANC is also shown in detail results for each frequency band and situation. Additionally, we display graphs that demonstrate how well the headphones isolate sounds across the whole frequency range.
On our website, we also include other details about the headphones, such as their sound quality, comfort, battery life, features, pricing, and availability, along with our isolation score and test results. We also offer links to places where you can purchase them offline or online.
