    • Performance testing to assist in fine-tuning the installation and assure contractor compliance with contract obligations.

    Sound Isolation / Privacy

    Achievement of proper sound isolation between adjacent spaces is essential in many types of developments, including multi-tenant offices and retail space, condominiums, open plan office space, etc.

    Spectra Tech can perform the following services:

    • If upgrading a facility,perform onsite testing at your facility, identify sources of objectionable sound transmission, and compare the test results to normally acceptable design standards
    • Develop strategies for achieving the appropriate sound isolation between all types of adjacent spaces
    • Recommend the specific sound isolation construction methods and materials which will best suit your particular situation, based on the frequency range and intensity of the noise we must attenuate
    • On new construction projects, we can work with other members of your design team to identify potential sources of objectionable sound transmission
    • Develop plans and specifications to limit sound transmission to acceptable levels and achieve the desired level of acoustic privacy

    Noise and Vibration Control:

    Sound and vibration are natural by-products of practically all mechanical, electrical, and human activity. Low levels of sound emission and vibration are usually ignored, and are accepted as part of our everyday background sounds. When a particular sound or vibration significantly exceeds the acceptable background level for a facility, except for the purpose of communication, we refer to it as "noise".

    Spectra Tech can perform the following services:

    • If upgrading a facility,perform onsite testing at your facility, identify sources of objectionable noise, and compare the test results to normally acceptable design standards
    • Develop strategies for mitigation of noise
    • Recommend the specific noise control measures which will best suit your particular situation, based on the frequency range and intensity of the noise we measure
    • On new construction projects, we can work with other members of your design team to identify potential sources of noise
    • Develop plans and specifications to limit noise and vibration emissions to acceptable levels
    • Work with your Mechanical Engineer to develop solutions involving HVAC systems

    Acoustics Optimization

    Many facilities, such as churches, worship spaces, auditoriums, classrooms, and meeting rooms are constructed with the express purpose of allowing audio communication involving a substantial number of people. Thoughts, ideas and feelings are exchanged through the medium of acoustics, in the form of speech, music, and other audio presentations. In these spaces, it is imperative that the acoustic medium be designed to optimize the effectiveness of the audio communications.

    Spectra Tech can perform the following services:

      Auditorium Reflections
    • Optimize room designs for speech and program intelligibility
    • Guide the acoustical design and construction of your facility
    • Perform onsite testing to quantify acoustic performance in an existing facility, and compare the test results to established performance standards
    • Working from blueprint drawings, we can predict key acoustical performance results in advance of construction, using our proprietary computer-based technologies (see link for example)
    • Identify any potential acoustical problems and address them before work is undertaken
    • Recommend optimium sound absorption, diffusion, and reflective surfaces
    • Recommend designs and specifications to achieve optimum sound isolation between the worship space and adjacent rooms or exterior noise sources
    • Assist your architect or interior designer in selecting appropriate construction materials, finishes, furnishings, equipment, and installation methods necessary to achieve desired results

    Sound System Optimization

    Use of a sound amplification system is necessary in many facilities where audio communication is necessary. The sound system must provide adequate inputs for all presenters and participants, must have appropriate control capabilities, and must amplify speech and music in a "true to life" manner for all in attendance. An example of our system design objective: "provide amplified sound level and frequency range for all listeners equivalent to natural / unamplified sound heard as if 8 feet from the presenter or performer."

    Spectra Tech can perform the following services:

    • If upgrading a facility,perform onsite testing at your facility, to identify the current performance of existing sound system(s), compare the test results to normally acceptable design standards, and determine whether any existing equipment might be salvaged and re-used
    • Computer-based analysis of building plans
    • Speaker layout based on the desired frequency spectrum output
    • Specify sound amplification and recording capabilities
    • Determination of whether any existing equipment might be salvaged and re-used
    • Consultation with system users re: input devices (microphones, control consoles, processors, etc.)
    • Coordination with electrical engineer for the primary AC power circuits, as well as standby power supplies for systems used for
      emergency purposes.

    Visual Presentation System Optimization

    The use of projected images as a part of presentations is now considered "mainstream." As the popular saying says: "A picture is worth a thousand words." To be effective, visual images must be large enough, clear enough, and bright enough to be viewed by all those in attendance at services. Often, the presentation is to be is broadcast or video-taped.

    Spectra Tech can perform the following services:

      photo blank
    • If upgrading a facility, determine whether any existing equipment might be salvaged and re-used
    • Optical design - we can optimize physical positioning of projectors, screens, and monitors for viewer line-of-sight, projected image light levels, and projected image size for viewers, etc.

    Lighting System Optimization

    Architectural Lighting

    The importance of lighting is often underestimated in the design of buildings. Lighting determines what we see, and how we see it. Your building and each architectural feature must be carefully illuminated, in order to convey the complete visual impression which you desire. Spectra Tech uses more than simple light to illumination its subject matter:

    • Color
    • Intensity
    • Position
    • Shadow
    • Dynamic Animation

    Spectra Tech can perform the following services:

    • If upgrading a facility, determine whether any existing lighting fixtures and control equipment might be salvaged and re-used
    • Design facade lighting, multimedia facade system, and control system to achieve the project's "statement"
    • Identification of lighting zones and requirements for illumination of individual locations
    • Consultation with system users re: lighting fixtures, control panels)
    • Coordination with electrical engineer for the primary AC power circuits, as well as standby power supplies for systems used for
      emergency purposes.

    Lighting for Services, Presentations, Performances, and Video Recording

    When a facility utilizes a visual presentation or recording system and features speech presentations or performances by choral groups or musicians, proper illumination and control of the light levels is essential.

    Spectra Tech can perform the following services:

    • If upgrading a facility, determine whether any existing lighting fixtures and dimming control equipment might be salvaged and re-used
    • Design lighting and dimmer system to coordinate and control all lighting within the room
