![]() ![]() QP400 can be configured to connect multiple radio and communication systems. This feature provides the user with confidence that a high level of protection is being achieved. QP400 automatically performs a FIT TEST of the in-ear headset to ensure that a good level of hearing protection and clear two-way communications are obtained. With the exception of impulse noise testing above 160dB (explosions), testing has been conducted on human beings to assure accurate and realistically reliably results. QUIETPRO® has undergone many extensive and rigorous evaluation and assessment programs by independent test and validation organizations in Europe, Australia and the United States. This highly stable digital ANR system automatically activates (only when required) and cancels out the rumbling of the low frequency noise from sources such as armoured vehicles (tracked and wheeled), large engines, boats, fixed wing aircraft and helicopters. QP400 incorporates digital Active Noise Reduction (ANR) that provides further attenuation for low frequency noises in additional to that provided by the foam ear tips. Overall passive attenuation of the foam tips - SNR 34dB (EN352-2). QUIETPRO® attenuation > 40 dB for Impulsive noise protection. QUIETPRO® is designed to allow for intelligible communication in high noise environments up to 110-115dB. When the dangerous noise is no longer present, QUIETPRO® immediately restores full hearing capability. The QUIETPRO® is developed to only attenuate what is absolutely necessary and only for as long as the protection is needed. QP400 continuously adapts to the noise environment, always providing the correct level of protection, but never over protecting. Vital for their personal safety and security. It also enables the user hear sounds around them ensuring that retain their localized situational awareness. QP400 allows the user to enhance their natural hearing so that they can hear sounds that cannot be heard with their ears alone. More than 63,500 of these original QUIETPRO systems have entered service with a variety of Government user groups in 15 countries worldwide. QP400 is designed using the core processing architecture and algorithms developed for the successful QUIETPRO and QUIETPRO+ systems. With automatic configuration of the interface to the device connected, the correct equalization (matching) of the interface is assured without any user intervention. QP400 connects to multiple two-way radio, platform intercom, soldier navigation solutions, sniper or gunshot detection systems, smart cell phones or personal music devices. QP400 ensures mission (safety) critical two-way communications are received clearly and accurately, first time in all noise scenarios. Mission Safety Critical - Two-way Military Communications Hearing protection that adapts to the noise environment to permit the user to hear sounds around them – when safe to do so. QUIETPRO® QP400 from Honeywell Safety Products is an advanced Intelligent Hearing System that provides high-levels of ‘verifiable’ hearing protection. This unique combination of features is targeted to enhancing the capability of the soldier performing his duty in harsh and dangerous environments, and to allow for the use of one system only for all combat scenarios. It adds no weight to the head and is fully compatible with all military ground, vehicle and ballistic helmets and CBRN protection gear. QUIETPRO® significantly improves communications and situational awareness in noisy surroundings while protecting the users’ hearing. QUIETPRO® QP400 is an intelligent digital communication headset and high-level hearing protector for military use. Intelligent Hearing Protection and Communication Systems Honeywell Safety Products draws on the corporation’s exceptional technology and innovation capabilities to develop new materials, electronics, sensors, and communication systems. We are backed by the powerful global resources of Honeywell International and its $1.5 billion corporate R&D budget. Honeywell Safety Products has become the world’s largest personal protective equipment (PPE) provider, with annual revenues of more than $2 billion. ![]()
