Sonilus
Sound in Design (Capstone) - SP 2022
The Sonilus is an analog sound masking device designed to combat the effects of noise pollution in urban environments. This device is designed to satisfy the needs of both analog and digital sound masking device users, by combining the sound quality and volume adjustment of analog sound maskers with pitch customizability present on certain digital sound maskers.
The pitch shift is produced by the origami inspired expanding body, which increases the amount of space the sound can resonate within the device.
The device is designed to be used in various different scenarios, ranging from workflow to rest, and even simple interior decoration.
The user may also customize the device’s tone to fit any soundscape in any environment, and mask noises such as vehicles, conversations, and footsteps.
How To Use
Process Work
Prior to creating the scope of the design, extensive research needed to be conducted on the topic of noise pollution, its prevalence, and some of the ways humans have learned to counteract its effects- such as sound masking, noise cancellation, and acoustic dampening.
Eventually, I came to the conclusion that the most universally effective and accessible method of noise reduction was the utilization of sound masking devices.
Studies conducted by several research institutions as well as the EPA conclude that about an average of 1 in 3 people are affected by noise pollution every day.
On a self conducted survey of 76 urban city residents, 48 of those individuals utilize sound masking devices on a daily basis.
Of those 48 individuals that use sound masking devices, 32 preferred analog sound masking (fan based) and 16 preferred digital sound masking (speaker based).
Pain Points
- Noise pollution is a significant obstacle to both mental and physical well-being.
- Although analog sound maskers have good sound quality, they lack customizability preferred by some users.
- Digital sound maskers, although offer customizability for sound type and frequency, they lack the organic sound quality desired by many.
Design Opportunities
- Create a sound masking device that can cover the needs of both analog and digital sound masking device users.
- Create a device that looks visually appealing, and can blend into its surroundings as a decorative object.
According to the survey participants, most of the analog sound masking device users prefer analog because of the distinctive organic sound quality created through air flow. But some of the digital sound masking devices prefer speaker based because of the customizability such devices offer, such as different sound frequencies- not just volume.
Thus, I sought to create an air flow based sound masking device with both volume and frequency control, to satisfy the needs of both types of users.
Much of the physical process work of the Sonilus revolved around model testing and determining the best type of outer shell form factor capable of expanding and contracting, creating the change in sound frequency.
Eventually, I landed on the form factor of origami tessalation springs, which can both expand/contract in addition to being aesthetically pleasing. Although traditionally created with paper, this form factor can be created with any soft elastomer, such as TPU or silicone.
