Audio visual Design

We create your audio visual design to maximize your investments, keeping the galloping changes of technology in mind, best possible future proofing topology is in our audio visual design methodology. To fine tune the audio visual design process, we use Computer Aided Design Software to bring ideas on to the drawing board for your perusal. We review the audio visual design with you at different stages of the project, at the time of proposal, prior to ordering the product and construction phases. Fulfilling your expectations is our mission. We believe audio visual design of your system should be done at concept. It is easy, economical and better to finalize your expectations on the drawing board first. Once you approve the audio visual design to integrate your whole home automation we start the process.

Our audio visual design package include the following categories:

• Equipment layout diagram using Floor Plan
• Ceiling Equipment layout diagram
• Lighting zones & Load schedule diagram
• Viewing angle for optimum viewing
• Cable Riser diagram
• Elevations
• Audio connection diagram
• Video connection diagram Control connection diagram
• Network diagram Power allocation diagram
• Equipment Rack layout

 

Five Steps of the audio visual Design Process we follow as guideline in our designing process:

• Programming (Discovery)
• Conceptual Design (Design Development)
• Detailed Design (Construction Documentation)
• Installation (Construction)
• Post Installation ( Training & Warranty)

 

Features of Rooms

Sight Lines

• Audience
• Projection System
• Ceiling Height
• Screen
• Windows
• Finishes within the room
• Static display systems

Light Level

• Quantity
• Quality Electrical Power
• Grounding
• Phone and Network

 

Features of Rooms

• Microphones
• Loudspeakers
• Speech
• Program AV Interfaces and controls
• Acoustics
• Ventilation
• Structural Mountings
• Sight line parameters
• Average seated head height=4”-0”
• Average Eye height=3’-6”
• Determine the lowest visible point on the front wall
• Determining Image Size

-Viewing requirements of the Task

-Text size to be displayed

-Viewing Distance

-Image Height

-Aspect Ratio of the Image

 

Determining Image Size

• What is the Task

– To View : General Viewing

—  Image HT = Distance to the furthest viewer/8

–  To Read : Detail Viewing with Clues

—  Image HT = Distance to the furthest viewer/6

–  To Inspect : Detail Viewing without Clues

—  Image HT = Distance to the furthest viewer/4

• How close the nearest viewer be?

– The Image Width

 

Viewing Area

• The Good viewing area is within 45° of the projection axis or within a 90° viewing cone
• The acceptable viewing areas are within 45°  of the edge of the Image

 

Screen Design & Brightness

Borders on the edges of the screen help increase perceived brightness as well as help mask keystone error.

Screen projection brightness is measured in foot lamberts (Lumen/ft2 reflected)

Foot lamberts measure how bright the image will appear on a particular screen

ANSI Lumes=Ave. LUX * meter2  screen area

Screen foot-lamberts= (Projector ANSI lumens x Screen gain)/ft2 screen area

 

How Bright a Projector to use?  

SMPTE standards for theatre is 16 foot-lamberts max

SMPTE standard for direct view CRT is 50 foot-lamberts

Minimum contrast guideline is 10:1 ratio of on-screen brightness with surrounding area.

When looking at screen and working at the table Contrast ration should not be more than 3:1. More than 3:1 contrast tires the eye pupil.

 

Room Acoustics

Reverberation

–   NRC Absorption

–   Types of materials

–   Mounting of materials

–   Location

Diffusion

–   Increases distribution of the direction of sound

–   Diffused sound energy is distributed in time

–   Concrete wall with different cut/wedges is good diffuser

Echoes

 Room Acoustics

Normal RT60

–   Range from 0.3-0.8 for TV studio

–   Range from 0.7-0.9 auditorium for speech

–   Range from 0.5-1 for recording studio

–   Range from 1-3 for house of worship

–   Average living room is 0.5

 

Room Acoustics

Very Quiet to Quiet – NC-15 to NC-25

Moderate Noisy to Noisy – NC-26 to NC-45

Very Noisy -NC-46 to NC-56

Extremely Noisy – NC-57 to NC-65

 

Projects

There are Four Variables to a project

–   Scope: what is to be done

–   Quality: how well is to be done

–   Resources: personnel, material, tools, $$

–   Time: before, during and after

 

Define the Scope of work

Client expectations

Equipment list

Audio visual design Drawings

Demarcation with others working on the project

 

Plan the project

–        What must be done?

–        Who will do it?

–        How will it get done?

–        How much will it cost?

–        Do we need anything to complete the job?

 

Execute the Plan

Order materials & equipment

Monitor materials & equipment orders

Schedule facility and resources

Mobilize resources

 

Monitor and control progress

–         Are we on target?

Schedule

Performance expectation

–         Are we on budget?

Creative expenditure can improve schedule

–         Should the plan be changed?

Alternate products, stage the event, Refine the design.

 

Close the Project

What was done well in the project?

What should be improved upon?

What did we learn for future?
