  • SubTrap 18/22 .

    So, you bought a new sub and were trying to reach the musical blue sky...but you ended up with the subwoofer blues. You thought maybe deep bass was supposed to sound this way: drab, sluggish and boring. You keep the volume turned down and the crossover set low so your sub can “support” the bottom end without drowning out the music. But... you know you can do better. It's time for a subwoofer stand! Now you can "raise" your subwoofer to its full performance potential! The SubTrap is more than a simple vibration isolation stand. In addition to isolation, it absorbs excess bass (the BAD bass) and decouples your subwoofer from room modes. Once you hear the difference, you’ll never go back! Only from ASC. Installation and integration could not be easier; just slip a SubTrap underneath your sub. You'll instantly improve sonic detail, changing “fuzzy” playback into a richly detailed picture by lowering the running noise floor of the room in the all-important low bass range. You'll hear musical bass lines you never knew existed! Utilizing our patented Isothermal technology to boost the low bass performance, the ASC SubTrap should be the foundation of your acoustic control plan. From there, build your musical experience with rich harmonics and a lush, immersive soundstage.

  • QuickSoundField

    The QuickSoundField is a near field recording environment that allows you get the most sound, at the highest quality, into your mics. The QSF can transform the center of an ordinary untreated room into a lush recording space. It works great for all types of recordings, from tracking drums and vocals in wide open spaces to close miking guitar amps in close quarters. The QSF uses the principles of "sound fusion" to maximize the quality - and quantity - of sound reaching your mics. StudioTraps encircle the mic and talent create a recording space that is sonically decoupled from the room acoustics. Inside the QSF the sonic quality remains consistent from one setup to another without the need for studio notes. The talent is free to move around while recording and no one can hear the change in position. Most important is that what the talent hears inside the QSF is what they hear in the control room.
  • ASC SoundPlanks are the perfect companion to ASC TubeTraps for complete control of the acoustics in your room.  After the bass range is under control, the SoundPlanks further improve imaging and flutter echo without taking up any floor space.  Install approximately 16" on center near early reflection points for optimal results.  Install with less spacing for a more "dry" sound. SoundPlanks can be used in many applications:
    • High-End Listening Rooms
    • Recording/Mixing/Mastering Studios
    • Offices
    • Auditoriums
    • Band Rooms
    • Churches

  • HalfRound TubeTrap Isothermal

    The Half Round TubeTrap Isothermal model is a versatile evolution of the TubeTrap, allowing the same sound-busting power of the TubeTrap to be wall or ceiling mounted. The unique and effective design of Half Round TubeTraps combine broadband absorption, diffusion, and directional control of sound reflections to reduce noise levels while maintaining room brightness and enhancing image resolution. This design approach results in compact and modular units that can be placed in patterns on walls, ceilings, and in corners of any room.

    All Half Round TubeTraps are made with our Patented ISOTHERMAL technology

  • MonitorStand

    A monitor speaker stand is a studio must. A typical monitor speaker on a stand is located about half way between the floor and the ceiling. The floor/ceiling bounce returns back to the monitor out of phase. This imposes a phase cancel effect on the speaker’s output; for example, the first cut is around 74 Hz for 8’ ceilings, causing the engineer to boost 74 Hz in the mix unnecessarily. The ASC MonitorStand "stack" upsets the vertical symmetry in the room and minimizes this negative acoustic feedback. The lower Trap (Base) absorbs bass, whereas the upper Trap (Top) stops short of the ceiling and vents bass. The combination eliminates the phase cancel effect and lets the engineer work in a linear environment. Whether part of an ASC ATTACK Wall system or in a stand-alone configuration, ASC MonitorStands give you more than just simple support for the physical placement of your monitoring system; it also dramatically improves the monitor and room accuracy. Works with nearly every monitor speaker made today, from a little Focal CMS65 to the large Genelec 8361 or Westlake BSSM12 -- and everything in between.

  • The MatrixPanel, designed for use when your listening position is near a wall, softening the sonic reflection of the wall without deadening the sound.
  • WallDamp .

    With the IsoWall System, you get walls & ceilings that reduce sound transmission by 20dB or greater compared to standard interior walls. That is more than quadruple the perceived sound volume reduction, which is what makes our wall system the highest available using standard single-stud construction. Internally, the walls are tempered to move with the air pressure of bass frequencies. Where a rigid wall would shudder at high volumes (similar to the distortion in an overdriven speaker) and raise the noise floor of the room considerably, an IsoWall will "bend" with the pressure and absorb the sub bass sound wave while allowing the bass waves to reverberate cleanly.

  • dRC-1

    High performance audio rooms are so quiet inside and so acoustically fast in response that as the music plays, sounds and tones come and go quickly. When a tone slightly shakes the floating wall, which happens to be the same frequency as the resonance of the supporting stud, the stud is stimulated onto movement.

  • The ASC Acoustic Test Signal

    To explore the musical intelligibility and the sonic image-ability of your audio system... Play the MATT test first over headphones and then in your room.  You hear a scale of rapid tone bursts that any HiFi system should be able to reproduce.  Your system could but it can't because the room keeps getting in the way.  Then concentrate on the sound stage.  It's a mono signal and the image should stay stage center, tight and focused, but it doesn't. This test is a rapid gated slow sine sweep.  It demonstrates the musical clarity vs frequency of the HiFi system in your room.  In some ranges of sound you will hear strong rapid dynamic sound level changes while in other ranges the tone bursts blur together in reverberant chaos.  You can also hear the more familiar peaks and valleys of your room.  Then play it again but this time close your eyes and concentrate on the sound stage of this perfectly mono signal.  In some tone ranges the image stays put; stage center, small and tight, where it belongs.  But the next tone range sees the image lose focus and fluff up into a ball of fog. And yet another sees the image up and wander off, flying around the sound stage like Peter Pan. The objective of performing the MATT test in your listening room is to determine where you might move your speakers, listening position, and/or where to add acoustic treatment to your room to obtain the highest quality sound possible from the components in your listening environment. How fast is your room? Most audiophiles know how loud they can play their room before it begins to break up. Even the speakers have a breakup threshold, above which we begin to hear cone breakup and box buzz. The MATT test is an easy way to ring out your room without risking doing damage to structure or gear due to sustained power at one frequency. At lower sound levels it checks out the room acoustic part of your listening experience, sorting out clear dynamic bandwidths from blurred bandwidths.

  • When the manufacturer can’t supply the hush kit you need, we can.

    Acoustic Sciences Corporation also makes custom solutions to help reduce the noise any kind of high-noise air handler or cooling system. ASC will engineer an add-on unit designed to seamlessly fit your existing air intake and/or exhaust. High noise air handler situations, such as those found in the cooling systems for large electronic switching centers, can cause hearing loss for unprotected workers on site. Our goal is to reduce the noise level to OSHA acceptable levels or better. Row after row of electronic signal processing cabinets are usually cooled by vented updrafts from the air conditioning plenum under the floating floor, but not always. Hot spots in equipment cabinets get extra cooling from air flow booster fans and blowers which always makes unplanned-for noise. That’s when a custom run of Acoustic Sciences Corporation's matching noise baffles need to be designed, built and delivered. It’s a big team project, with their engineers, technicians and managers on one side and our in-house staff on the other. Typically our clients will ship or sometimes hand-deliver the blueprints and functioning parts of their noise making equipment. We also partner with a local group of talented specialty fabricators so we get the high quality metal fabrication and painting we need. The goals, along with the long list of constraints, are lined out by our client and we go to work. We measure the noise, and determine how it is made. We design and build models improving each one until it works as desired. We ship it to the client for further testing. After back and forth exchanges, and we all come to an agreement the production version of the baffle is designed. A sample is made and shipped. After it’s approved we fabricate the production run and deliver it. Our happy customers include many smaller manufacturers and a few big ones, such as: FAA commercial and military airport ASR-9 radar sites, FAA air route traffic control center ARTCC sites, Westinghouse radar equipment, Raytheon contracts, Harris Corp Voice Switcher Cabinets, Liebert Air Handlers and Power Conditioners, EMC Corp’s huge hard drive memory cabinets, and for Texas Instruments, we developed our smallest baffle, about 3/8ths inch square, mounted to the flying head of their last heavy duty impact printers.

  • Professional Recording In-Line Mufflers

    Recording studios and rooms with quiet requirements need dampened HVAC supply and return ducting. ASC designs and manufactures in-line mufflers, noise-reducing outlet diffusers, and duct baffle inserts. Most residential and commercial HVAC equipment creates too much noise for use in recording studios. We build specialty mufflers that combine built-in bass traps with standard treble range absorbing panels. Our solutions not only deliver air into rooms silently but also reduce the acoustic crosstalk between rooms through the HVAC ducts.
  • If you have outdoor compressors, transformers or HVAC equipment in close proximity to residential areas, odds are good that you need an ASC SoundFence. There are many types of noise barriers available, but none of them absorb noise like the SoundFence. They also share a common theme: high cost. The SoundFence gets the job done better while costing a fraction of comparable barrier systems.

ASC and Bruce Swedien have joined forces to recreate the original kick drum cover used for Billie Jean. ASC and Bruce Swedien have joined forces to recreate the original kick drum cover used for Billie Jean. Recorded in 1982, Billie Jean is considered to be one of the most revolutionary songs in history. And now, decades later, the secret was finally revealed.

    #18 out of the 20 best drum sounds of all time

    Because of what Bruce came up with, the sound that was created was recently voted #18 out of the 20 best drum sounds of all time! Here is an excerpt:
    #18. Billie Jean: Michael Jackson (1983) from the album “Thriller” Whilst other artists in the early 80s seemed to be going bigger, flashier, more processed and more extravagant with their drum sound, for an artist to release something so natural and minimal was a real gamble. Producer Quincy Jones wanted to cut the 29-second introduction (which was the longest one ever created at the time) and yet it is undoubtedly the drum sound that has since gone on to define the record, and all within the first few beats. Jones had earlier instructed engineer Bruce Swedien to create a drum sound no one had heard before. Read full article here
