Fader Plugs: The World's First Adjustable Mechanical Earplug



What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

In 2015, CEO and Founder, Blaise Delfino, M.S. - H.I.S., embarked on a mission to aesthetically refashion and perceptually transform the use of hearing protection; Blaise wanted to remove the fear and stigma associated with wearing earplugs. Prior to starting graduate school, Blaise further conceptualized the device with his father, Dr. Gregory Delfino, Au.D., CCC-A. Dr. Delfino has been a clinical audiologist for 30+ years and immediately recognized the value that Fader Plugs would provide to individuals exposed to noxious noise. 

During graduate school, Blaise and Team Fader competed in the PA State System Business Plan Competition (2016), as well as the TecBRIDGE Business Plan Competition (2017). Fader Plugs placed first in both competitions, winning over $120,000 of cash and in-kind services. Competing in both business plan competitions procured the resources Fader Plugs needed to pursue and conclude research and development.

Team Fader partnered with Creative Engineering, located in Bronxville, NY to develop the Fader Plug proof of concept and working prototypes. The team continued to build its infrastructure and added a Director of Creative Development, a Director of Public Relations, an advisory board with notable business professionals, a legal team, and an accounting team. Fader Plugs has immersed itself into its community and works with educators from East Stroudsburg University and with the local chamber of commerce to participate in events, exhibit, and glean more press. 

We have selected the Kickstarter crowdfunding platform in an effort to gauge our consumer market and to fulfill our budget needed to publicly launch.    

Research and Development 

Fader Plugs chose Creative Engineering as the primary engineering firm to bring the Fader Plug to life. Below is an overview of the tasks associated with each phase of product development:

Phase 1 (Completed May 2016) : Research & Concept Development 

Creative Engineering will start the project by seeing what has already been done and coming up with solutions. 

Phase 1 Tasks: 

  • Perform additional patent search 
  • Research applicable technologies 
  • Purchase reference materials as appropriate 
  • Identify key challenges 
  • Develop conceptual solutions to the challenges

Phase 2 (Completed September 2016) : Proof of Concept Prototype

In this phase, Creative Engineering will design and prototype the chosen concept from the previous phase. It is possible that some iteration may be required before the Design for Production phase can begin.

Phase 2 Tasks:

  • Engineer the chosen concept for prototyping 
  • Obtain earplug “blanks” as required for test prototype 
  • Obtain raw materials and custom parts 
  • Fabricate, assemble and debug the test prototype  
  • Client to test the performance of the prototype

Phase 3 (Completed May 2017) : Design for Production

Once a prototype design has achieved an acceptable level of performance, the product will be engineered for production.

Phase 3 Tasks: 

  • Develop the aesthetics: our Industrial Designer will create renderings of the look 
  • Finalize the aesthetics 
  • Engineer the two versions of the product in CAD in every detail 
  • Review the design 
  • Adjust the design based on feedback 
  • Obtain prototype quotes  
  • Create drawings and documentation of the design for costing and patent application

Phase 4 (Completed July 2017) : Validation Prototypes

Before production can begin, the designs created in the previous phase must be prototyped and tested to ensure the products will perform as designed.

Phase 4 Tasks:

  • Obtain prototype parts 
  • Assemble and debug prototypes 
  • Review prototypes 
  • Fader Plugs to perform validation testing

As indicated above, Fader Plugs has completed all phases of product development. This allows our team to effectively and efficiently deliver your universal and/or custom Fader Plugs in a timely manner. 

The Team 

Blaise Delfino is the CEO and Founder of Fader Plugs, LLC. Blaise thought of the Fader Plugs concept while running on the beach in Long Beach Island, NJ in the summer of 2015. He embarked on a mission to refashion the perception of hearing protection. He, and Team Fader have won two business plan competitions including the 2017 TecBRIDGE Business Plan Competition. Since the initial development of Fader Plugs, Blaise has put together an advisory board and added more team players to his business dynamic. He grew up with the influence of hearing healthcare practitioners with his father being a Doctor of Audiology, and his mother being a Pennsylvania licensed hearing healthcare specialist. The family currently owns Audiology Services, LLC, of which Blaise, upon undergraduate completion, decided to work and develop his business and clinical skills. He studied to receive his certification as a Pennsylvania Hearing Healthcare Specialist. Blaise later graduated from East Stroudsburg University in Spring 2017 and was the graduate commencement speaker. He completed his Master’s of Science in Communication Sciences and Disorders, more commonly known as Speech-Language Pathology. Aside from thriving in business and progressing as a young entrepreneur, Blaise is a musician; he plays the piano and acoustic guitar. As a practitioner of creativity and artistic production, he creates and continues to write his own music. Blaise’s audio engineering career led him to successfully produce a number of songs, including the iTunes charting hit, “First” feat. Blaise Delfino. Outside of the business world, Blaise loves to read. He finds it imperative to work on yourself harder than you work on your business. He preaches and practices personal development, utilizes the law of attraction in his daily life, attends networking events, and enjoys his hobbies of photography and video editing. He enjoys going to the gym and spending time with his family and friends. Blaise is a Lehigh Valley local and is adamant about being a part of the community’s business development efforts; he has recently joined the Greater Lehigh Valley Chamber of Commerce.

Dr. Gregory Delfino is the President and Founder of Fader Plugs, LLC. Dr. Delfino is Blaise’s father and further conceptualized the Fader Plug as far as design, structure, and functionality. His educational credentials and thirty plus years in the field of audiology warrants Dr. Delfino as an expert in the field, able to diagnose hearing deficits, communicate treatments and instruct on hearing preservation methods. Dr. Delfino received his Bachelor’s of Science in Political Science from Seton Hall University, and then completed his Master’s of Science in Audiology from Montclair State University.

Noise Reduction Rating (NRR) and Personal Attenuation Rating (PAR) Attenuation Ratings/Testing

Noise Reduction Rating (NRR) was developed by the EPA in 1978 as means of assigning a numerical value to the level of hearing protection a consumer could expect from a specific product. The assumption was that the higher the numerical value, the greater the protection. A single number rating would be affixed to the product to inform the consumer that an estimated level of noise reduction for the 98th percentile of protection was available to the users when properly fit into their ears. However, all too often earplugs are not properly fit into the ears by the wearer yielding hearing protection less effective than expected. The NRR was designed for the application of C- Weighted noise levels. Occupational noise exposure standards utilize an A –weighted measurement protocols. The NRR overestimated the actual protection afforded by a particular earplug or ear muff (Berger, Franks & Lindgren, 1996) . As a result, NRR “derating methods have been proposed by the National Institute for Occupational Safety and Health (NIOSH) to approximate real-world performance until the labeling system is changed or fit testing is required (NIOSH,1998).

Personal Attenuation Rating (PAR) is the process by which an earplug or earmuff is fit to an individual and attenuation performance is measured using a probe microphone placed in the ear canal in tandem with the Hearing Protection Device being tested. PAR testing is designed to be used with A weighted noise exposure measurements. PAR testing instills confidence in the appropriateness of the Hearing Protection Device selection, allows for ear specific fitting adequacy, binaural attenuation values and provides an educational opportunity for the correct insertion method for maximum attenuation for the device being evaluated.

Risks and challenges

Fader Plugs is in a unique position in that we have completed all phases of product development, as well as product validation. Fader Plugs have been tested amongst colleagues, friends, and family. The challenges are not regarding the product itself. While product development has concluded, there are a few challenges that we may encounter. However, we have a solution for each challenge:

1.) Durability: We do not currently have long term durability claims. However, the team is working with our manufacturers to establish a test center and protocol to ensure quality control and durability.

2.) Noise Reduction Rating: Fader Plugs works with an in-house Audiologist who specializes in noise reduction rating (NRR). Once the first round of the Fader Plugs are manufactured, we will be sending them to be tested and obtain an accurate NRR rating. The NRR rating is a subjective measure, which means it sometimes lacks reliability. However, personal attenuation rating (PAR) will also be conducted. This is an objective measurement of attenuation and provides greater accuracy with regard to overall noise attenuation.

3.) International Service Delivery (Custom Fader Plug): In order to receive your custom Fader Plug, you will need to visit an Audiologist or licensed hearing instrument specialist. Through Fader Plugs' affiliate, Audiology Services, we have the tools to overcome this challenge. Audiology Services works closely with Starkey Hearing Technologies, the global leader in hearing healthcare. Fader Plugs will be able to direct our international consumers to a trusted Audiologist and/or license hearing instrument specialist to take impressions of their ears.
