| Summary, etc. |
Sleep deprivation affects cognitive function, mental health, and well-being. Soundproof earmuffs help improve sleep by reducing noise, but conventional ones often use synthetic materials that are environmentally harmful. This study investigates the viability of using Coconut Husk (Cocos nucifera L.) and Scallop Shells (Annachlamys striatula) as sustainable materials for an engineered soundproof earmuff, EcoSnooZze. The study evaluates different material compositions-ranging from 100% coconut husk to 100% scallop shells-by testing their soundproofing capacity across a frequency range of 250 Hz to 4,000 Hz. Using experimental research design, prototypes were developed, tested using a sound level meter, and analyzed through ANOVA to determine significant differences in performance. Findings indicate that optimal noise reduction, comparable to commercial earmuffs, can be achieved using specific concentrations of coconut husk and scallop shells. Among the experimental treatments, 100% coconut husk demonstrated the highest soundproofing capacity (77.72 dB), closely matching the commercial earmuff (76.32 dB). ANOVA confirmed significant differences (p < 0.05), identifying 100% coconut husk as the most effective natural alternative. This study underscores the potential of sustainable materials for noise reduction, with future research needed to enhance product durability, optimize material ratios, and evaluate comfort for extended use Tested ratios included 25% coconut husk and 75% scallop shells; 50% coconut husk and 50% scallop shells; 75% coconut husk and 25% scallop shells; 100% coconut husk; and 100% scallop shells. |
