P11227 Exhaust Acoustic Tuning
INTRODUCTION:
This document describes and serves as a template for preparation of a Project Readiness Package. The objective of the Project
Readiness Package is to document customer needs and expectations, project deliverables (including time frame), budget, and
personnel / organizations affiliated with the project. It will serve as the primary source of information for students necessary during
the Planning phase to develop a SD I plan and schedule including specific deliverables and due dates. The Project Readiness Package
will also support Faculty evaluation of project suitability in terms of depth, scope, and student / faculty resources by discipline.
In this document, italicized text provides explanatory information regarding the desired content of the sections indicated by non-
italicized, bold, capitalized headings. If a particular aspect of a section is not applicable for a given project, it is only necessary to
indicate that by entering N/A (not applicable).

Project Overview (1-2 paragraphs that provide a general description of the project: background, motivation(s), customer(s),
and overall objective(s).):
Enthusiasts of off-road vehicles, motorcycles and racing, in general, consider exhaust “tone” a
redeeming value. From Harley-Davidsons to AMA Superbikes, a strong exhaust note is a beloved
sound. But even these riders like to listen to Pink Floyd and P!nk when cruising so a “flick of a switch”
to quiet their bike’s “tone” may seem like a good idea! (My personal peeve is my neighbor’s lawn
mower on a Sunday afternoon….)
Sound system manufacturers such as Bose® have developed products such as Engine Harmonic
Cancellation System http://www.bose.com/controller?url=/automotive/innovations/index.jsp to improve
sound quality by minimizing engine sounds; see their website videos. In contrast, the mission of this
project is not to design a perfection of sound such as this Bose product, but rather a “brute force”
solution to quiet engine noise at its source; the exhaust.

Staffing Requirements: (use WBS and associated resource estimates to summarize anticipated staffing needs)
Discipline (number) Skills required (concise)
Research, evaluate, characterize, design and test the feasibility of acoustic
attenuation of the exhaust from an internal combustion engine.
Study tradeoffs or relationships between noise attenuation design and associated
power usage to achieve this.
1. Basic understanding of physics and electrical engineering, ability to
EE 3
conduct “sound measurement” and summarize for team
2. Basic understanding of sound acoustics and electrical engineering, ability to
conduct a noise reduction methods for internal combustion engines, and
summarize for team usage
3. Ability to think out of the box to conduct feasibility experiments for “proof
of concept”. “No such thing as a bad idea!”
Same as above but with engine systems and exhaust sounds (i.e. pressures) as your
core of understanding.
ME 1
1. An understanding of internal combustion engine dynamics.
2. Design and build test bench fixtures to conduct experiments.
Continuation, Platform, or Building Block project information (Include prior project number and title and to what
extent previous results are being incoarporated):
P11221
DETAILED PROJECT DESCRIPTION:
Customer needs:
P11221 Website.
Understand the basic physics involved in sound measurement and noise generation. Summarize
standard procedures to objectively quantify sound level and quality. Specify and procure a cost effective
measurement system.
Benchmark existing noise reduction proposals; collect, analyze, and summarize available materials;
WEB, Car companies, Invention Sites… etc
Understand the fundamental sources of noise generation from the normal operation of an internal
combustion engine. 1. Discrete frequency sources, 2. Broad band or white noise sources
Propose noise reduction methods for each noise source
Conduct basic feasibility demonstrations of potential solutions
Quantify possible noise reduction opportunities.
Customer deliverables (Customer requested milestones, progress reports, and expected product):
As per MSD I and II courses.
Customer and Sponsor Involvement (Describe role of customer and sponsor in the project, planned participation in
design and project reviews, etc.):
o Dr. Nye and Prof. Hanzlik will be available for weekly one hour meetings with the team to
provide customer input and technical support for internal combustion engine knowledge.
Regulatory requirements (i.e. UL, IEEE, FDA, FCC, RIT):
None

Project Budget and Special Procurement Processes (Provide all budget details and processes associated with
expenditures):
Based on Team’s design proposal.
Intellectual property (IP) considerations (Describe any IP concerns or limitations associated with the project): possible,
team is being asked to review the current state of patented technology.
None.
Other (Describe potential benefits and liabilities, known project risks, etc.):
DETAILED COURSE DELIVERABLES:
From the Course Deliverables document, extract general and discipline specific deliverables that are appropriate to the project. This
should provide clear guidance to the students on what it expected.
PRELIMINARY WORK BREAKDOWN:
Describe the anticipated distribution of general tasks to be accomplished by project participants based on perceived skill set
requirements. This should justify the requested skills and number of students from each discipline.
GRADING AND ASSESSMENT SCHEME:
Describe how the grading rubric relates to expectations and deliverables. The impact of project enhancements and improvements
from baseline should be clearly articulated.
THREE WEEK SDI SCHEDULE:
List expected activities in the first three weeks. Highlight any project specific activities that may not be part of the generic course
syllabus (e.g. customer visits).
Review P11221 Website.
Work with guide and customer to converge customer needs; this will be an iterative process of matching what the customer
needs are against what the team can realistically deliver in 22 weeks
Conduct a week 3 review that would consist of a summary status on the current set of customer needs. It is expected that
measureable work has been done on the first three needs, and the team is ready to “discuss” customer need #4.
