Bass Shakers (Part 2): Motion Platforms Are Bass Shakers on Steroids

Bass Shakers (Part 2): Motion Platforms Are Bass Shakers on Steroids

In the first part of this article, our exploration of bass shakers introduced us to haptic sensations, which add the dimension of structure-borne vibrational energy to audio reproduction. At a concert, we see the performers, hear the music, and feel the amphitheater resonate with the bass. For home theaters, this “tactile” component adds another dimension (sometimes referred to as 4-D) to reproduce the impact of explosions, engine sounds, and thunder through by use of vibration. In this article we will focus directly on those haptic components. This article was originally published in audioXpress, May 2014.

Good Vibrations (Part 2) - Dealing With Unwanted Vibrations

Following a first R&D article, where Norman Varney discusses the basic principles of unwanted vibrations in audio playback environments, in this second part he writes about what his research found to be effective ways to counteract those effects. The article details the evaluation process and extensive measurements that lead to the creation of various products that AV RoomService provides when helping clients with their acoustic problems.

Good Vibrations (Part 1) - The Basic Principles of Unwanted Vibrations

In this article, Norman Varney discusses the basic principles of unwanted vibrations in audio playback environments. "When we play back audio, we only want to hear sound waves created from the electromechanical vibrations produced by the loudspeaker. They are the result and intention of the artists. They are the original signals. These are good vibrations. However, for this article, we will focus on the basic principles of unwanted vibrations of audio playback environments," states Varney in the article introduction, originally published in audioXpress, August 2019

IsoAcoustics Introduces DELOS Series of Isolation Wood Blocks for Turntables and Hi-Fi Components

IsoAcoustics is recognized worldwide for its speaker isolation solutions both for professional studio and high-end applications. In the high-end space, the company was repeatedly asked to provide a solution for turntables, which they did with the OREA Isolator series. Now, IsoAcoustics expanded the approach with a complete platform solution. The new DELOS series of solid-wood isolation platforms, was designed specifically to isolate turntables and audio components from any interference caused by external vibrations and resonances.

IsoAcoustics’ Introduces Stage 1 Isolators Designed for Stage Monitors and Musical Instrument Amplifiers

At the 2019 Winter NAMM show, IsoAcoustics will introduce the Stage 1 Isolators, the latest in the company’s acclaimed line of isolation solutions, now in a design for loudspeakers, stage monitors, subwoofers and musical instrument amplifiers. Specially designed for touring musicians and bands on any budget, the new Stage 1 isolators effectively eliminate the vibrational variables experienced while playing onstage in a variety of venues and locations, enabling musicians to have consistent, clear sound, night after night.

New IsoAcoustics OREA Bronze Isolators for Lighter Audio Components and Turntables

New IsoAcoustics OREA Bronze Isolators for Lighter Audio Components and Turntables

The OREA Bronze was now added to the OREA series of Isolators from IsoAcoustics, announced the Canadian company. The new OREA Bronze Isolators provide extraordinary levels of isolation for high fidelity audio components and turntables and are now available. In order to create this newest addition to the OREA series, IsoAcoustics had to lower the weight threshold in the series in order to achieve adequate isolation performance with lighter components including amplifiers, DAC's, CD players, small speakers and turntables.

Vibrotextile Surround-Body Experience Bypasses Eardrums Enabling Users to 'Hear' Music via the Brain

Vibrotextile Surround-Body Experience Bypasses Eardrums Enabling Users to 'Hear' Music via the Brain

Not Impossible Labs, a California-based company, made a presentation of its "Music: Not Impossible (M:NI)" applied Vibrotextile technology that translates sound onto the skin through vibration, allowing users to feel the nuances of a music-listening experience. Initially inspired by deaf music fans, M:NI's use during a concert produces a dramatic effect for all participants, regardless of their hearing, delivering a shared 'surround body' experience.

Speaker Design: Driver-Induced Vibrations

Speaker Design: Driver-Induced Vibrations

In order to generate a sound, a driver must vibrate. But what happens when one or more drivers are placed on the same baffle? In the exact moment that the cone begins to move, it starts to transmit — through the frame and the screws — vibrations to the cabinet and to the other drivers that are fixed on it. This article discusses multiples approaches to handle the problem, working on material, dimension, thickness, density, rigidity, and damping of the panels to be used. This article was published in audioXpress, February 2008.

The Rheintacho Stroboscope Shaking Test for Quality Control

Rheintacho Messtechnik proposes a practical solution for vibration quality control tests with a portable stroboscope solution, using its RT STROBE qbLED series. The German company specializes in highly efficient solutions wherever speed must be measured, monitored or indicated. Its portable stroboscope range allows non-contact checking of electrical and mechanical components on a vibrating table, in a safe way.

Primacoustic Recoil Stabilizers: A Solid Speaker Base

Primacoustic Recoil Stabilizers: A Solid Speaker Base

Primacoustic's Recoil Stabilizers incorporate four key components to achieve the desired combination of isolation and stability. Isolation is provided by a high-density, open-cell urethane foam base that prevents resonant frequencies from traveling from the loudspeaker to the supporting shelf. This open-cell foam is dense enough to support the weight of the speaker, and soft and thick enough to provide isolation from the surface below.
