Silicone Earplugs Effectively Protect Workshop Workers from Noise Damage

Silicone earplug is a kind of a noise-reducing product that is plugged into your ears for hearing protection. It can be used to reduce noise interference and is generally worn by industrial workers working in very noisy environments.

A pair of reusable silicone earplugs is displayed.

Features

Three layers of umbrellas structure increases its sealing performance and make it comfortable to wear.
Long earplug cord helps you plugging it into your ears quickly.
Made from soft and durable silicone material.
One size fits the majority of wearers.
High attenuation. SNR (Signal-to-Noise Ratio) is 32 dB.
Compatible with Dual-Ear Validation Hearing Test System.
Easy to wash and clean.
Supplied in re-sealable pillow-pack for ease of use.
Available in both corded and uncorded versions.

Application

Silicone earplugs are ideal for high to moderate noise exposure levels, and are suitable for all frequency noise in a wide range of industrial workplaces and leisure environments, including but not limited to the following industries:

Automotive
Chemical & pharmaceutical engineering
Construction
Heavy engineering
Metal processing
Textile
Woodworking

Attenuation Performance

Item	Reference Value
Frequency (Hz)	63	125	250	500	1000	2000	4000	8000
Mf (dB)	29.2	29.4	29.4	32.2	32.3	36.1	44.3	44.8
Sf (dB)	6.0	7.4	6.6	5.3	5.0	3.2	6.0	6.4
APVf (dB)	23.2	22.0	22.8	26.9	27.3	32.9	38.3	38.4
Technical notes APVf (dB) is equal to Mf minus sf in dB. Mf stands for mean attenuation value frequency. sf stands for standard deviation frequency. APVf stands for assumed protection value frequency.
