Safe listening devices and systems

Gap analysis
•Early 2016
Work on umbrella

•2Q 2016
Drafting completed
• July 2018 (C)Aug. 2018 (A)
ITU edition launched
•Nov. 2019 (P)
WHO edition launched
•Feb. 2019 (P)
How we got here
• Europe: Existing hard-threshold standard;Evolving sound-dose standard
• Big void elsewhere• No guidance on communication to device users
• Formal approval on 29 Aug.2018 as an international standard: Recommendation ITU-T H.870
• ITU edition published in Nov. 2018• Translation available into the six
UN languages
What else? And where from now?
• WHO & ITU Toolkit (2019/02)
– What can different stakeholders do (governments, industry, civil society)
• Derivative work:
– H.871 - Safe listening guidelines for personal sound amplifiers
• Advocacy, awareness
• Standardization front:
– HSTP-CONF-H870: Specification on how to check compliance to H.870
– Future improvements to H.870
– New standard on safe listening in public spaces

ITU-T Recommendations
Selecting a test laboratories
▪ Accredited Testing Laboratory on ISO/IEC 17025 (first, second or third party)
▪ Joint ITU/IECEE Testing Laboratory recognition procedure, certification scheme
▪ ITU test events (call for bid among Testing Laboratories)
▪ ITU conformity testing Pilot projects (e.g. develop test specifications, identify test labs, conduct tests)
Technical experts on ITU-T H.870 are needed for selecting Testing Laboratories
Common criteria for ITU-T Technical experts
• Expert from ITU members
• Deep technical knowledge and experience on ITU-T H.870 and relevant test specs
• Experience in testing of ICT products against ITU-T H.870 and competence to review Test Report(s)
• Do not have conflict interest with assessed TL (NOdirect/contractual, personal/corporative relationship)
• An experience in ISO/IEC 17025 and knowledge of IEC/ILAC rules will be an advantage
Potential approach
Appoint ITU-T technical experts who have relevant expertise (to assess TL and/or a bid review)
Recognize/identify testing laboratories (TLs) which have competence to test ICT products against ITU-T H.870 using relevant test specs
Test ICT equipment in TLs on compliance with ITU-T H.870
Register products in ITU Database (create a QR code)
ITU Product Conformity Databasehttp://www.itu.int/go/tcdb
ICT Products tested against ITU standards using ITU test specifications
The database contains different categories of ICT products (more than 500 entries):
• E-health devices• Mobile phones• Ethernet services• IPTV• MNP systems
The database is used by different stakeholders. For instance (not limited to):
• Vendors of ICT products (expansion of sales)
• Suppliers (mitigation of risks under supplier’s responsibility)
• Testing laboratories (promoting TLs expertise)
• Customers (increasing brand loyalty)
BACKGROUNDMany mobile phones do not work properly with car’s HFT’s system and thereby significantly degrading the speech quality of the complete system

GENERAL STATISTIC• 58 mobile phones (state-of-art devices)• 89 tests (55 Narrowband and 34 Wideband)• 30 % mobile phones comply with the requirements ITU-T P.1100&P.1110 (1st event)• 22% mobile phones comply with the requirements ITU-T P.1100&P.1110 (2nd event)
LIST OF BEST PERFORMERS
COMPATIBILITY OF MOBILE PHONES AND VEHICLE HANDS-FREE TERMINALS
Product compliance with ITU-T H.870 (safe listening)(increasing brand loyalty)
