Boeing 737 Ng 4 Sound - the stunning and incredible sounds and fx of the REAL CFM567b 24 and 28 engine variants.

Recorded at a number of locations including private aprons, hangars and taxiways these accurate, digitally balanced 16 bit files represent the most stunning sounds of the REAL Boeing 737-Ng you will hear.

Engine sounds from the flight deck were recorded on real flight decks. Start up sounds were recorded outside remote maintenance hangars.


Introductory note from our Ng 4Sound recording engineer:

"In reality, you can barely discern the start up sound of CFM567b engines from the flight deck. This is due to the fact that a lot of noise is heard on the deck after start up. During TOR and in flight, wind, packs, air cond etc; are all chasing postion on the EQ. What we heard we designed to sound (and feel) the same. The tonal value of some ranges, like engines starting up is lower than the tonal value of the mid to high range sounds of the packs (and is bass-resisted) so the sound is felt more than it is heard (but you will hear it like the pilots do). Sound of the engine startup in the FS Ng cockpit is barely discernable as a low whine. To truly bring out the real Ng sound, we added the correct amount of bass and then took the sound back to the cockpit for testing. On some of the exterior sounds it was difficult to be in a place where there was only the sound of a single Ng aircraft. When we did find a location, the sound seemed unreal, so we mixed the sound with the real sound of a number of ng aircrafty taxiing in a natural environment - after all that is the sound you will hear at the airport in real life. What we got in the end wasbetter than we could have imagined.
The similarity was uncanny."

Note: Our Lead Developers conclusion for playback (he mixed the final sets) was that these sounds would be best played on good, bass/woofer-equipped speaker systems to get as close to that "reality effect" as possible:

NG 4Sound was designed professionally using PRO edit and mixing facilities and tested on high-end systems and low end laptop sound environments. Each CFM567n Sound Set:

  • Replicates exactly the real Ng CFM567b engine sound.
  • Emulates the closest sound fx to a real Ng engine.
  • Includes a broad range of Special Effects for each engine set.
  • Choice of STEREO or MONO sound sets (stereo for 16-bit enhanced qaulity or MONO for faster frame rates/low end machines).
  • Sound Configuration Installers help you install your sounds to your chosen payware or freeware aircraft easily and simply. (Manual installed to the ARIANE folder on your FS2004 install). There are so many features on the Boeing 737-Ng 4sound set that, to include them all would take up a number of pages. Here we include just a few of the effects:


  • Runway “clack” and “clunk” sounds are now modelled as you hit the many different (virtual) ruts and joins of the runways and taxiways! In FS, these features were not modelled but, Ariane bring you another FIRST with Ariane Boeing 737 Ng 4Sound RWYFX; now you can actually HEAR the real sounds of ruts, joins and center lights on the runways and taxiways, at all stages of taxiing or take off and landing. Take off rolls sound awesome! Taxiing takes on a new level of realism!
  • The sound of the front gear droning and whining can be heard onpressing the [G] key as it is stowed away (this is quite discernable since it is under the Captain and the First officers seats).
  • On retraction or deployment, both drone and wind rush can be heard. (The clunk of the gear nose doors closing is also mixed into the nose gear edit for further effect).
  • Packs sounds. The loud and discernable sound of the packs can be heard at different levels and the air pressure or airspeed/throttle speed is changed. The finished effects are stunning.
  • Familiar Ng APU background sounds add to the ambience.
  • Landing sounds, Wheel strike and front gear rattle are all included.
  • “Clunks” & “clack” of compressing nose gear is heard on landing.


  • Position yourself outside and you will note the whine of the engines preceeded by the familiar sound of the CFM567b starter throw.
  • On the CFM567b 28 file set, the heavy roar of the engines can be heard on full power after firewalling the throttles.
  • Runway “clack” and “clunk” sounds - as in real life - will also be heard from outside at the point of touchdown and during roll out or taxiing!
  • The complete process of startup can be heard. Both engines will phase with each other as the start up process concludes.

Many other sound effects are also featured including AP disconnection, flap drone, touchdown sets, roll and roar, wind noises, packs, air cond, APU, glideslope warning, etc;
