Noise cancelling headsets in business class

[Guest Michael]

I am just curious as to know if they are still being used or not?

QF use BOSE ones in First & Business class.

[Guest Michael]

Oh I see not sure what MAS use though.

Wads of cotton perhaps ?!

Speculation on my part here, not flown in J before

Noise canceling headphones are used in MH's F and J class too.

[BC Tam 2]

OK, I stand corrected

The one thing I picked up when flying Business Class for the first time (on upgrade) and subsequently flying in Economy class is that these noise cancelling headphones are worth it... You get sleep, can hear the baby crying at a whisper so yeah... Well worth it.

 

I think SIA also use Bose ones but they are Dolby NR I know that.

How can they help you sleep - they only work when switched on playing something??

Didn't see any when I flew J to EWR last November.

 

Didn't see any when I flew F from LAX to KUL in December either.

They don't have to play anything...it helps to muffle the engine drone, amongst others, something like a white noise.

Noise canx headphones are really good to have on when you are trying to sleep on an aircraft.

 

I just plug them in, turn down the volume, and just hear the soft noise of the engines. Dont even hear when people next to you are moving about or when someone walks down the Iles.

 

[Guest Michael]

Are the headphones going to make a return do you think?

The term is anti-noise. There is a built in mic that picks up ambient sound and samples it, then reproduce it exactly 180 degres out of phase and two sounds of the same frequency but with opposing phases will cancell out each other.

 

The Bpmbardier Q series propjet has the feature built in the cabin where speakers positioned in the cabin produces anti noise in much the same way. The difference is amazing when an ON-OFF comparo is done.

There is one mechenism in the plane where it analyze the noise, then produce polarisation reversed waveform to cancel the noise by interference. Same applies to noise cancelling headphones where it produce inteference to cancel the noise

Does that mean one will have to speak louder to be heard in the Bombardier Q aircraft ? Or is the system optimized for specific bands of wavelengths ?

 

Fascinating, if it can be applied to the better half's nagging noises .....

[Guest Michael]

What happened to them on MAS?

[BC Tam 2]

What happened to them on MAS?

Cost reduction attributable to BTP / BTP2 ?

I think Brennan Raj answered the question already?

[Guest Michael]

Ok I will wait until I fly on April 5th.

No. there is a system logic built in for it to 'anti-noise' only against constant frequencies such as the drone of the engines, whooshing sound of airflow, whine of the turbines. Conversations are normally of varying frequencies over a short period so the effect of sound cancellation is not noticeable. Anyway, nobody converse with headphones covering the ears unless intercom is used.

What, you haven't paid recent attention to youths of today ?!

Thanks for clarification !

How do you tell the difference between a noise cancelling and normal headphone?

[Nik H. 3]

There will be words to that effect on the headphones. ie Sony MDR XXXX noise canceling headphones.....

[Guest Michael]

I think MAS was bringing them back in phases.

[Guest Michael]

The airline is advertising on their Italian site they still have them.
