Spares Noise Protection Guide

Introduction: Why Hearing Protection Matters
Each day, millions of workers, performers, and everyday people are exposed to hazardous noise levels without realizing the long-term risk. Noise-induced hearing loss is not only permanent, it's entirely preventable.
Spares High-Fidelity Earplugs were created to help solve this silent crisis. Designed to reduce harmful frequencies while preserving natural sound clarity, Spares provide industry-standard protection for anyone exposed to high decibel environments.
Whether you're on a construction site, working a concert, managing equipment, or riding a motorcycle, Spares offer the comfort, confidence, and protection you need.
How Hearing Works & How Noise Damages It
Sound enters the outer ear, vibrates the eardrum, and passes through tiny bones into the inner ear where the hearing nerve converts it into brain signals. When noise is too loud, it damages nerve endings in the inner ear. That damage is irreversible.
Spares reduce harmful sound levels by an average of 30 dB, especially in the frequency range most responsible for long-term damage: 1,000 to 8,000 Hz. This includes engine noise, loud vocals, tools, and more.
Recognizing Dangerous Noise Levels
Noise is hazardous when:
- You need to shout to be heard
- It causes your ears to ring
- It hurts your ears
- You experience temporary hearing loss afterward

Frequency Matters
Human speech falls between 300 and 4,000 Hz, but damaging sounds often occur between 2,000 and 8,000 Hz — where hearing loss typically starts.
Spares are tuned for high-fidelity reduction in exactly this frequency range, making them ideal for:
- Live music environments
- Power tools and machinery
- Vehicle and aircraft engines
- Crowded cityscapes
OSHA Standards & Hearing Conservation
According to OSHA and Cal/OSHA:
- 85 dB average exposure requires a hearing conservation program
- 90 dB mandates hearing protection and noise control
- 95+ dB requires hazard controls or limited exposure time
Spares help employers meet these standards by providing reliable 30 dB reduction in occupational settings.
Time + Loudness = Risk
Hearing loss is about intensity and exposure time. The louder the sound, the less time it takes to do damage:
- 90 dB: 8 hours max
- 95 dB: 4 hours
- 100 dB: 2 hours
- 115 dB: 15 minutes
Spares extend safe exposure time and reduce risk of cumulative damage.
Why Spares Work When Others Fail
Many hearing protection devices are uncomfortable, hard to insert, or ineffective due to poor fit. Spares solve all of these problems:
- Four cup sizes included for the perfect seal
- No deep insertion needed
- Comfort-fit silicone base doesn’t irritate or fall out
- Stainless steel filter chamber reduces damaging frequencies without blocking clarity

Already Have Hearing Loss?
Even if you already suffer from hearing loss or tinnitus, it's never too late to protect what you have left. Spares help preserve remaining hearing and prevent worsening conditions.
Proper Use = Maximum Protection
Removing hearing protection for even 30 minutes during an 8-hour shift drastically reduces its effectiveness. Spares are easy to keep in place thanks to their comfort, fit, and low-profile design.
Common Myths Debunked
- "My ears will get used to it." No, they’ll just get damaged.
- "Cotton works just fine." Not true. Cotton only blocks ~7 dB.
- "I won’t hear people talking." Spares preserve clarity better than foam or muffs.
