So, that’s how the tech works and the different modes available. ‘Transparency’ offers the user something in the middle of ‘off’ and ‘on.’ Noise cancellation will still be active, but sounds will not be reduced as much. ‘On’ gives the user full noise cancellation, meaning background sounds will be suppressed and limited, and the user will hear significantly less of them. It means noise canceling is not active, and background sounds will not be reduced in volume at all. There are different modes of noise cancellation available: off, on, and transparency. This is because noise-canceling technology does not actually completely eradicate background noises but significantly lowers the volume of them so they can’t be heard over the audio being played through the AirPods. Sometimes this noise-canceling frequency can be heard as an almost inaudible buzz, somewhat like white noise. It’s quite technical, but this technology is used in all noise-canceling headsets.ĪirPods also have another internal microphone facing inwards, into the ear, which will detect and neutralize any sounds generated from your own head, too! It works via a secondary microphone on the external face of the AirPod, which will detect and neutralize any incoming sound with ‘anti-sound,’ which is actually a low-level sound wave of the opposing waveform to that which is incoming. The addition of the noise cancelation technology was a wonderful design feature by Apple. Unfortunately, first and second-generation AirPods don’t have any noise-canceling capabilities, so this article really only relates to third-generation AirPods and AirPods Pro. However, it is worth noting that the issue could actually be caused by the AirPods getting confused by the noise cancelation settings, and ‘canceling out’ your voice, and amplifying background noises, which is the reverse of what’s meant to happen! Noise Canceling Tech in AirPods and AirPods Pro But by limiting their capability to switch between two microphones, this should be greatly reduced. Now, simply select which AirPod you want to use as the microphone.īe warned: this is not a certified fix! You may still find that occasionally your AirPods are picking up and amplifying the wrong sounds. To do this, head to Settings > Bluetooth > ‘Your AirPods’ Info (i) > Microphone. This significantly reduces the likelihood of the headphones accidentally picking up and amplifying the wrong sounds. Some users, however, have found success by switching the “Pickup Microphone Automatically” to just left to right AirPods. Unfortunately, there is no way to manually lower the gain of the inbuilt mic. If you can imagine: a passing truck beeping its horn, or the clunk of a mug being set down on a hard surface, or a zipper being done up at close range – any of these sounds amplified by a high-gain microphone and projected into the ear of the listener would be most unwelcome! How to Fix This Of course, with it being so powerful, these sounds will be amplified down the phone line and appear in the recipient’s ear as loud as the voice! Of course, this works well to amplify the speaker’s voice and transmit it over the phone call, but sometimes the microphone may pick up other background sounds too. In an attempt to remedy any problems that might arise from the microphone being unable to detect speech or to only pick it up at incredibly low volumes, the AirPods are fitted with a high-gain microphone in the bottom of the stem. As you can imagine, this could present a major problem if the headphones were to be used for hands-free calls as well as just listening to audio. The stem of the AirPods, where the microphone is positioned, barely extends out from the ear certainly nowhere near the mouth of the user. One of the main possible causes for an overbearing amount of background noise on phone calls conducted via AirPods may be down to the fact the microphone fitted in the headphones is exceptionally powerful.
