The second good headphones used on the aircraft are industrial noise protection earmuffs and earplugs provided by airlines.
The best headphones used on the aircraft are industrial noise protection earbuds and high-quality earbuds.
This report on in-structure
I did a flight test using industrial ear guards and earplugs during long flights. (
This can also be in-line)
The original idea came from two facts :-
Therefore, the combination of the two should be able to well suppress noise at all frequencies.
The result is the cost of noise-
No need to cancel earplugs.
First let\'s talk about noise, which is measured in dB, the power of each frequency, and then averaged on all the frequencies we can hear.
For an example of the noise level, see a comparison example of the noise level.
Aircraft cabin noise ~ 80 dB (“In-
Cabin noise levels when commercial aircraft fly
Think about the noise level of the food mixer
A \"quiet Street\" is about 50 dB.
The acceptable maximum intrusion level is 55 dB for the sleeping environment (A)(U. S.
Ministry of Commerce, 1985).
Therefore, ideally, we would like to reduce the noise level to about 50 dB over the entire frequency range.
That said, we want to reduce the noise by 30 dB over the entire frequency range, but especially at higher frequencies, which makes it difficult for people to distinguish what they are talking about.
So it\'s hard to watch movies.
For the perspective frequency, the hum in the speaker is 50/60Hz, and the middle C (C4)is ~261Hz, C8 (
4 degrees high)
Yes ~ 4186Hz, the sound on the phone is within the range of 300Hz to 3400Hz.
People with good hearing can hear about 20Hz to 20,000Hz, although only the top headphones and speakers can cover this range.
The industrial ear guard is designed to reduce noise.
People with higher ratings, both oven 80 and NNR ratings, are better, but they all do a better job of suppressing higher frequencies rather than lower ones.
For example, the chart on the back of the 3 m Peltor H10A Optime 105 Earmuff box states :-
Reduce 21dB noise at 125Hz, 37 db at 500Hz and 41 db at 8000Hz. Noise-
On the other hand, cancel the headlights, noise-
Canceling headphones and earbuds works best at low frequencies and can\'t actually cancel high frequencies at all.
For example, is it worthwhile for Forbes magazine to \"cancel the noise headphones?
Reported Bose (
Earmuff headphones)
Noise reduction with 45dB at 160Hz, with \"only\" 20 dB at 500Hz and 0 dB at high frequency, I . E. e.
No active cancellation at high frequency.
Bose noise in fact
Cancel the headset (and others)
Actually, when the noise-
Open cancel.
The ideal air travel headset that combines an industrial ear guard with a noise reduction headset should be the \"ideal\" headset for aircraft use.
This is an industrial ear guard with good passive noise suppression at high frequencies, placed on a set of noise cancellation earbuds with good active noise
Cancel at low frequency. In-
The flight test is over two 14 hours.
Pacific flight, Sydney to San Francisco, return by joint Boeing 787-9 Dreamliner. 787-
The Dreamliner should be quieter than the previous model.
On my way to San Francisco in Sydney, I was in seat 27.
This is the aisle exit row behind the wing.
I found a lot of high frequency wind and air in this row.
In addition to the low frequency engine noise, the noise is also adjusted.
In this section of the trip, I used the industrial ear guard purchased from Bunnings, UniSafe Folding Hi-Vis Earmuffs (SLC80 27)
~ $22 plus earplugs from airlines.
It\'s just passive noise suppression, no active noise-cancelling.
I found the UniSafe earmuffs to be very tight and not the most comfortable, but snug fit ensures good high-frequency noise suppression.
I found that they eliminated all the high frequency wind noise and reduced the engine noise to less noticeable low frequency background rumble, just to reassure people that the engine is still running.
Think of the waves in the distance breaking out on the beach.
Although it fits, I need to adjust the position of the earmuffs from time to time, I used it for 12 hours and found that the sound of the wind was so bad that I didn\'t want to take them off.
The earbuds provided by the airline were not very comfortable, but the earmuffs were kept in place and the result was that I could easily watch a movie with less than half the volume.
Removing the earmuffs makes it difficult to understand the sound at that volume level.
Health authorities are concerned that there is no value in using large-capacity headsets in high-noise areas.
At the very least, it\'s tiring to just watch a movie with the included earplugs, which can easily give you a headache.
Overall it was a successful trip and didn\'t get a headache for having to watch a large volume of movies or close-up earmuffs, but I was looking for a pair of more comfortable ear guards and some noise
Cancel earplugs for the return trip.
On the overnight return flight (
San Francisco to Sydney)
I have classes in the 4D business class in front of the plane.
This is the quietest part of the cottage, but there is still a lot of wind noise.
For that leg I used 3 m Peltor H10A Optime 105 Earmuff purchased from Amazon for $20.
I found these things not so tight on my head, but it was hard to adjust.
Some user reviews reported that these earmuffs were easily broken.
My ears fell off and the black ears popped around, but it bounced back again.
I paired them with the audio. Technica ATH-
Quiet Noise-Cancelling In-
Amazon ~ Us50 headphones.
These earbuds are more comfortable in my ear than the economic earbuds the airline has released, but audio
Technica has a short lead.
Also, I didn\'t notice any noise cancellation when they were on.
Just a slight increase in volume.
So I wouldn\'t recommend them for noise. cancelling.
The only positive aspect is-
Line volume control.
The passenger sitting next to me put a pair of Bose on the headphones.
He was surprised by the effectiveness of the ear guard in eliminating cabin noise, and at the same time I noticed that Bose did a better job of suppressing the nose of the low frequency engine.
However, when Bose noise-
The cancel is on, it introduces a high frequency hiss, and I think I feel annoying when I try to sleep.
It also means that I will have to watch more movies.
I was thinking of buying a pair of Bose QuiteComfort monthly noise
Cancel the earbuds, but considering that the earbuds provided by the ear guards and airlines work well on the first leg, about $250 (A$350)
It doesn\'t seem like a good deal for Bose earbuds.
Also, some of Amazon\'s user reviews complained that QuiteComfort 20 earplugs failed or broke early.
So I compromised and bought the audio. Technica ATH-ANC23 instead.
Waste money.
On the union business class you will get headphones with two plugs, but one of them has a smaller diameter.
This means that you can\'t insert headphones or earbuds using the \"standard\" two plug adapters.
However, there is an easy solution to simply plug the headset into the larger one of the two headphone holes in the small corner at the top of the seat.
This is good.
The seat in the business class was changed to a flat panel.
If you are about 6 feet tall, the seat behind the big head has more side foot space than the other seats.
That said, if you have another seat in front of you, it will take up most of the walking rooms.
There are two rows of seats in this extra walking room, first row and fifth row.
Both rows are next to the service area and the toilet, but with the ear guard on you won\'t hear much.
When I put on the ear guard, I managed to sleep in the reclining seat.
39 \"x 17\" x 2 \"helps sleep (
100 cm x 43 cm x 5 cm)
A memory foam with a pillowcase on both ends, I use it to help smooth the seat profile when fully stretched, which turns into small lumps and bumps. (
I also found that memory foam helps hotel beds that feel like wooden boards. )
I have no earmuffs, earplugs, memory foam and pillows in my carry-on case anymore.
There are computers and toiletries in my backpack.
When you look inside
In the flying movie, the noise in the sound frequency range is the most intrusive.
Noise ranging from 300Hz to more than 3400Hz in understanding speech frequencies and higher frequencies can hinder understanding.
For example, to distinguish between \"failure\" and \"sales\", you need to be able to clearly hear the frequency above 3400Hz.
This is why it is most important to suppress high-frequency wind noise on aircraft.
A pair of comfortable cheap industrial ear guards, the higher the rating the better, your favorite earbuds are everything you need for a quiet and pleasant flight.
The ear guard does a very good job of suppressing noise at 500Hz, even better at higher frequencies.
In the frequency range of 300Hz and 3 m Peltor H10A Optime 105 Earmuff, the background noise is effectively reduced to the background noise of \"quiet Street.
Ear guards can also prevent earplugs from falling off when you move around. Active noise-
Canceling the earbuds should further reduce the hum of the background engine, but also introduce high-frequency hiss, which in my opinion is not worth the extra cost.
The ear guard certainly does a better job of reducing high-frequency wind noise than the Bose on the headset.
