The JSP Sonis Compact Hi-Vis Ear Defenders SNR 32 are exceptionally comfortable and hygienic, with a reflective head band for added visibility to colleagues in low light environments. They offer a SNR of 32, and are suitable for protection against substantial industrial noise, such as that produced by agricultural machinery.
What Can the Ear Defenders Do for Me?
The ear defenders have several useful features. These include:
- Performance: Outstanding acoustic engineering allows for an SNR of 31
- Comfortable: Headband is cushioned for comfort and allows for ventilation, ear cups can be tilted and adjusted to find and optimum fit
- Hygienic: TPE construction of ear defenders is easy to wipe clean
- Hi-Vis: Highly visible cups and reflective head band for added low light protection

Who Can Use the Sonis Compact Ear Defenders?
The orange ear defender has a medium attenuation factor at 107 - 111dB, and has achieved an SNR of 31. This means that the defenders are suitable for protection against substantial industrial noises and can be worn for long periods of time without developing fatigue. The following is a list of hazards and settings for which the ear defenders are suitable protection:
- Substantial industrial noise
- Construction and agricultural machinery
- Road works
- Forestry
- Engineering
Please note that one size of the ear defenders should fit most users.
What Is SNR?
SNR stands for simplified noise reduction, and can be used to compare the different level of noise attenuation offered by hearing protectors. To establish the acoustic pressure on your ears from a hazard subtract the SNR value from the average noise level measured. To avoid hearing damage this number must not go above 87dB.
What Certifications Have the Ear Defenders Received?
The ear defenders have undergone a variety of tests so you can be sure of your safety at work. They have achieved the following certifications:
- EN 352
- SNR: 32
- Low Frequency Noise: 21
- Medium Frequency Noise: 29
- High Frequency Noise: 35
What Do These Certifications Mean?
- EN 352: This standard specifies the requirements for ear defenders offering protection from excessive noises
The materials, inner leakage, minimum attenuation and several other factors of the ear defenders have been assessed and found to conform with the requirements for hearing protection. The ear cups have an attenuation of 107 - 111dB and an SNR of 31 which suits them to high levels of risk.
What Makes the Ear Defenders So Comfortable?
The ear defenders feature an over-moulded headband with a ventilated comfort area. Together with the ear cup cushions this provides the optimum level of pressure over extended periods of wear. The steel arms are adjustable so you can tilt the ear cups to find the right position for you.
