Lightspeed Excellent Service

Jay:

I just got a pair of the twenty3G and most of the time really love
them. Unfortunately, I now hear things I didn't before (I've been
using 15Ks) which makes me a bit unsettled -- the A&P and I are going
to do research on my engine...

One issue -- a popping sound as I'm taxiing and during takeoff. Don't
hear it again, but every flight so far, popping.

There's also a whine once in a while which I think is the final approach
of the ILS but it's been happening in other locations.

Once it warms up around here, I'll go do more study.

Are you sure that this popping is not the headsets? I have been using ANR
headsets for two years now, having started with Lightspeed 25XLs, then to
the 33Gs, and currently to Bose Xs.

Both the Lightspeed and Bose ANR headsets would occasionally pop, most
times during taxi and takeoff. It seemed to me that the popping was the
ANR circuitry's response to increased engine noise, either just after
startup or on takeoff.

I have to admit that the popping was much more common in the Lightspeed
models than the Bose, though.

I've not heard this popping sound, Blanche. I hope it's not your engine!

However, this does illustrate an issue I've always found funny, which is:
People who say they "Don't want ANR headsets because they want to really
*hear* the engine..."

What a load of malarkey, eh? You can hear the engine -- and anything else
going on in the plane -- 10,000 times better using ANR headsets, than
without them.

Heck, I've got a rattle that drives me NUTS at 23 squared. It's the
co-pilot's ashtray cover vibrating.

Try to hear THAT without ANR!

The only popping noise I hear is when I've got the canopy open, the wind
from the propblast tends to push the headphones off their seal a little bit
which causes a sort of a bleet from the ANR circuitry.

As for the whine, any chance your alternator/battery is a little weak at
low RPM's. With everything on in our plane, the we picked up of a
whine at extremely low power settings (it's in the intercom actually,
not the heasets themselves).

trust me, an open dooron a cherokee isn't easier to hear with
an ANR headset. First clue I had was a cooollllldddd breeze.

I had the opposite problem. While climbing to cruising altitude,
one of my exhaust tubes broke at the flange on the cylinder. I
noticed that the engine sound had increased substantially, but
initially figured that the battery on my ANR headset had died. It
took a few moments for me to realize that I wasn't wearing my ANR
headset that morning.

I had an exhaust pipe break. I could hear a clanking. I took off the
headsets so I could hear it better, and then I couldn't hear it over the
rest of the engine noise. Putting them back on I could hear the clank
again.
