Final Sound Garden Design

Abstract[edit]

The purpose of the Sound Garden is to demonstrate to the user the physical relationships between wavelength and sound in a safe, interactive, and understandable way. The Sound Garden satisfies the weighted criteria specified by the client for building a PVC xylophone-like musical exhibit. Designed by The Engineers That Could, The Sound Garden is a musical addition to the Redwood Discovery Museum's collection of wave-related exhibits. The design is a fun, appealing way for museum-goers of all ages learn about the physics of the sound. The Engineers designed the project for their Engineering 215 - Introduction to Design class at Humboldt State University.

Background[edit]

Ken Pinkerton from the Redwood Discovery Museum in Eureka, CA asked for an exhibit that will educate kids about the physical nature of sound.

Problem statement and criteria[edit]

The Redwood Discovery Museum needed a new musical exhibit to demonstrate the relationships between physics and sound. The objective of the Sound Garden project was to sustainably create and implement a new exhibit that was safe, educational, and appealed to all ages.

Description of final project[edit]

The Sound Garden is an instrument that displays the relationships between physics and sound. The exhibit uses varying pipe length in order to achieve desired notes. Re-purposed rubber spatulas are used as playing mallets. The display can be split in half for easy transport, and can be secured together with brass latches.

Testing Results[edit]

The Sound Garden is currently on display at the Redwood Discovery Museum. The staff is excited to officially open the exhibit on Tuesday December 5th, 2017.

Maintenance[edit]

With proper maintenance, the Sound Garden is expected to last 20 years.

Schedule[edit]

This is when to maintain what.

Daily
  • Visually inspect exhibit for loose pipes or damage


Weekly
  • Inspect playing caps, mallets, and draw catches for damage


Monthly
  • check for loose bolts


Yearly
  • Inspect tubes and frame for wear



Every 10 years
  • Re-coat stain


Instructions[edit]

This is how to maintain. The step by step how to template {{How to}} is most likely best for this part.

How to Do Something
ImageStep
Backpack frame bike trailer Step 1 : Assess the display for loose parts.
Aleiha's parabolic solar cooker Step 2 : Secure loose parts.

Troubleshooting[edit]

This is only how to troubleshoot basic operation. For complex issues, the solution might just say contact ________. It should be a table in this format:

Problem Suggestion
Pipes are not going into elbow assembly Loosen bracket
Notes are not playing clearly Inspect connection between elbow assembly and vertical pipes

Discussion and next steps[edit]

The Team hopes that kids visiting the museum will learn about the correlation of music and physics through the Sound Garden. The Sound Garden teaches this through ineractive use of the  different color coded pipes that vary in length as well as an educational music book that goes along with the musical instrument.

Suggestions for future changes[edit]

This is where to lay out suggestions for how to make the project function better in the future.
