3M ™ 1100 DISPOSABLE MOLDING PLUG WITHOUT CORD

What it is and why choose it

The 3M™ 1100 Disposable Molding Plug Without Cord is a soft, slow-recovery foam earplug designed to be inserted into the ear canal to help reduce exposure to harmful noise levels. It offers effective protection across all tested frequencies, making it suitable for use in high-noise environments. Its tapered shape and flexible polyurethane foam provide both protection and user comfort.

Main features

• Disposable earplug made of slow-recovery polyurethane foam.
• Single Number Rating (SNR): 35 dB.
• Provides effective attenuation across all test frequencies.
• High "L" value in HML data for improved attenuation at low frequencies (< 500 Hz).
• Slow-recovery foam makes insertion easier.
• Soft, flexible foam conforms to the ear canal for comfort and ease of use.
• Tapered design for easier fitting in the ear.
• Cordless version: 3M™ 1100.
• Compatible with the 3M™ E-A-Rfit™ dual-ear validation system.
• Meets applicable directives or regulations for CE and/or UKCA marking.

Technical specifications

Materials

• Earplug: Slow-recovery polyurethane foam.
• Cord: Not applicable (cordless model 3M™ 1100).

Attenuation data

Measured attenuation values for 3M™ 1100 (cordless) and 3M™ 1110 (corded):

Frequency (Hz)	63	125	250	500	1000	2000	4000	8000
Mf (dB) – mean attenuation	26.8	30.4	34.4	37.1	38.7	34.9	44.7	39.3
Sf (dB) – standard deviation	5.7	4.6	6.4	4.9	5.1	4.2	2.3	5.1
APVf (dB) – assumed protection value (Mf – Sf)	21.1	25.8	28.0	32.2	33.6	30.7	42.4	34.2

Global attenuation indices

• H (high-frequency attenuation value): 33 dB.
• M (medium-frequency attenuation value): 33 dB.
• L (low-frequency attenuation value): 31 dB.
• SNR (Single Number Rating): 35 dB.

H, M, and L describe the expected noise reduction for high, medium, and low frequency ranges, respectively, and SNR is the single-number value subtracted from the C-weighted sound pressure level (LC) to estimate the effective A-weighted level in the ear canal.

Applications and use cases

• Use in high-noise environments where reduction of harmful noise levels is required.
• Situations requiring effective attenuation across a broad range of frequencies.
• Applications where a comfortable, tapered, cordless disposable earplug is preferred.
• Workplaces using the 3M™ E-A-Rfit™ validation system for fit-testing hearing protection.
