One Team, Two Topics

ECN – Engineering Control of Noise ACCRAS – Amplification and

Connection of Conference Room Audio System

ILE – ECN Description

Engineering Control of Noise Converse with the residents to obtain an end-user

evaluation of the current difficulties present in the listening environment.

Measure the sound levels at multiple locations during meal hours.

Identify problem areas where noise levels decrease the signal-to-noise ratio at the diner’s ear and make speech intelligibility difficult.

Design and test engineering controls to decrease noise levels, thus increasing the signal-to-noise ratio and increasing speech intelligibility.

By meeting these objectives, we hope to improve the listening environment of the dining rooms at UPRC.

Current State - ECN

Currently, we have completed the following: Set out questionnaires asking for the resident

opinion on their listening environments in the dining room and at UPRC in general

Identified the areas in which we will sample and evaluate the noise levels.

Noise Sampling for the noise levels Recommendations for possible trouble areas

and devices to correct these problem areas will be completed.

A full report will be issued to UPRC to outline our recommendations and explain the measurements that were taken.

Sampling Locations

ACCRAS Description

Amplification and Connection of Conference Room Audio System

Survey the current available equipment Link the systems so that they are able to work

together when the room divider is removed. Research assistive listening devices (ALDs) that will

pair with the sound systems in these rooms to aid those with hearing impairments.

Provide UPRC with a cost/benefit analysis for the suggested ALDs.

Should they be purchased, implement the use of aforementioned ALDs.

Current State - ACCRAS

Currently, we have completed the following: Surveyed the current equipment Offered a solution to connecting the two

separate sound systems in the conference rooms

Researched assistive listening devices (ALDs)

Recommendations on methods to connect the sound systems have been made and will be reported to UPRC the end of the semester.

Recommendations for Assistive Listening Devices that could interface with the current system will also be recommended.

Continuity Plan Recruit 2-4 member project team

Students with majors or interests in Audiology and Industrial Hygiene

Pass on reports to next team to follow plan for the next semesters

Initial Phase

Mid Phase

Fall ’07

Final Phase

Spring ’07Described in presentation

Engineering control design and fabrication is to be completed. Provide UPRC with a cost/benefit analysis for the suggested ALDs. Should they be purchased, implement the use of aforementioned ALDs.

Late project goals from mid-phase and final testing and delivery reports should be completed
