MEMS Mics Pass $1B Milestone PORTLAND, Ore. — The market for  micro-electro-mechanical system (MEMS) microphones will top $1 billion  in 2014 for the first time, up 24% from $837 million in 2013, according  to  IHS Technology in El Segundo, Calif. 
   And although its growth rate is slowing it will maintain a five-year  compound annual growth rate (CAGR) of 18% until 2017 when it will top  $1.37 billion, according to IHS.  Yole Développement cites similar slowing growth rates, predicting a 13% CAGR out to 2019 when the market will top $1.65 billion.
   Driving growth today, both reports claim, is the wide adoption of  MEMS microphones in mobile devices, especially smartphones and tablets,  which are currently using multiple MEMS microphones to cancel ambient  noise, to provide high-definition (HD) audio quality for video  recordings and to improve the accuracy of voice command functions.  Burgeoning new markets for MEMS microphones include Internet of Things  (IoT), medical and wearable devices -- including smart watches and smart  glasses -- but the top buyers of multiple MEMS microphone set-ups today  are smartphone and tablet vendors -- principally Apple and Samsung. 
    By 2017, total MEMS microphone shipments will top 5.4 billion units up  from 1.9 billion in 2012, according to IHS. Yole similarly predicts that  shipments will be up to 6.6 billion units by 2019, up from 2.4 billion  in 2013.      Vendors are demanding, and getting, lower signal-to-noise (SNR) specs  for sensing the softest sounds, which when combined with a higher  maximum sound-pressure level (SPL) provides a wider dynamic range. The  market for HD MEMS microphones with the widest dynamic range will grow  at a faster rate than conventional MEMS microphones, according to IHS,  which predicts that HD MEMS microphones with SNRs of 64 decibels or  better will grow at a CAGR of 40% through 2017.
   Apple pioneered  the way by starting to use HD MEMS microphones with 64 decibel SNRs in  its iPhone 5 in 2012, prompting Samsung to follow suite with its  subsequent Galaxy S4 and Note 4 handsets, which, according to IHS,  together accounted to 96% of the revenue in 2013 for HD MEMS  microphones. HD MEMS microphones also enhance the accuracy of voice  commands to Apple's Siri and Google's Now, which has prompted other  vendors to follow suit, including Motorola which use multiple HD MEMS  microphones in its Moto X smartphone, according to IHS.
   Besides smartphones and tablets, HD MEMS microphones are also being  adopted by automobile makers -- to improve voice command accuracy -- and  by hearing aid vendors, notably the ReSound LiNX, which uses two HD  MEMS microphones to cancel ambient noise, improve sound clarity and to  enable them to double as music headphones using Bluetooth connectivity  with the iPhone.
   Separately, Invensense Inc. in San Jose, Calif. -- which recently  acquired Analog Devices MEMS microphone business -- made a strategic  alliance with Sonion A/S in Roskilde, Denmark, to become its primary  supplier of MEMS microphones. Sonion will have exclusive rights to sell  InvenSense MEMS microphone into the hearing-aid market, but InvenSense  will retain the right to continue selling its MEMS microphones into  other microphone applications.
