Recommendations on a quality clip on NC microphone? (lemm.ee)

I have to work in very noisy environments such as near construction sites, near very loud music or highways, and due to the nature of my job I need to be in a lot of online meetings.

I need a clip microphone with a really good noise cancellation feature that would filter all of the noise out leaving only my voice.

Any recommendations? I've found Hollyland Lark M2 but it seems it lets a lot of noise through anyway.

The human voice is a different frequency then construction noise though. Isn't it possible to build a microphone who filters out other frequencies? Maybe even customized to the users frequency?

I know nothing about this, just asking.

Sadly not. Form an audio frequency perspective, noise is many different frequencies. The human voice pretty much matches human hearing.

A voice is not one frequency, that's a tone. We've constructed systems that throw away much of the voice frequencies whilst still being understandable. Telephone calls, digital radio communication, etc.

That's not to reduce noise, it's to cram more calls across the same link. There's a side effect that does reduce noise to some extent, but not significant enough to remove construction noise.

Not the microphone itself, if you want you can apply a bandpass filter for the voice ranges in the system after the microphone.
