With the New Year well upon us, and the Grammy awards this weekend, Alex Wilson reflects on the musical year that’s just passed? In fact, this is something I find myself doing each year, as for the past seven years I’ve been charting the evolution of popular music recordings. It’s been well documented that recording became louder and more compressed throughout the 1990s, but that trend has more or less stabilised in the last decade .
Architectural acoustic diffusers are used to treat aberrations in rooms such as echoes. They do this by dispersing sound. Add frosting to a mirror and the light reflection gets indistinct, add a diffuser to a wall and sound reflections become blurred. The paper outlines a new approach to producing a diffuser that draws upon findings in metamaterial physics. By exploited the slow-wave phenomenon, we can create a diffuser that is shallower than many conventional designs.
A variety of methods are available for gauging the intelligibility of speech in the presence of background noise. Nearly all of these require the original clean speech to be known, so a comparison between that and the corrupted speech can be made. We developed a way of estimating the speech intelligibility that only needs the corrupted (noisy) speech. A Blind Source Separation technique is used to isolate the speech from the noise.
I told my radio producer that i'd record the links in my hotel bedroom. Shame my hotel is at the end of Birmingham airport runway. That's the traffic control tower in the background. https://t.co/UC6sNrMEVI
Muck Rack makes it simple to find people, tweets, or articles that mention any name, keyword, company, hashtag etc. We've compiled this guide to help you make the most of your search.
Selecting a term
Start searching tweets, articles from media outlets, articles mentioned in tweets, journalists'
names, titles and bios with some suggested searches:
Companies or Topics (e.g. iPhone, Microsoft)
Phrases (e.g. "cloud computing") — use quotes to keep the terms together
Twitter handles (e.g. @username) — returns those who have mentioned or replied to
Names (e.g. "David Pogue")
Hashtags (e.g. #sxsw, #london2012)
Bio details (e.g. vegan, Olympics, father)
Muck Rack's Advanced Search allows for many boolean operators.
Find results that mention multiple specified terms, use AND or
+. For example, ensure each result contains both Elon Musk and Mark Zuckerberg by
searching Musk AND Zuckerberg or Musk + Zuckerberg.
Use the operators OR or , to broaden your search when you'd like either of
multiple terms to appear in results. (This is the default behavior of our search when no operators
are used). For example, results will contain either cake or cookie by searching cake OR cookie or cake,cookie
Use NOT or - to subtract results from your search. For
example, searching Disney will yield results about the Walt Disney Company as well as Walt Disney
World Resort. To exclude mentions of Disney World, search for Disney -World or Disney
When using one of these operators with a phrase, enclose it in quotation marks. For example, you can
find results about smartphones excluding Apple's iPhone 4S by searching smartphone -"iPhone
Exact case matching or punctuation
If you're searching for a brand name or keyword that relies on specific punctuation marks or capitalization, you can
find results that match your exact query by adding matchcase: before the keyword you're searching for, like matchcase:E*TRADE .
Use parentheses to separate multiple
boolean phrases. For example, to find journalists talking about having fun in Disney World or
Disneyland, search for ("disney world" OR disneyland) AND fun.
An asterisk can be used to search for any variation of a root word truncated by the asterisk. For example, searching for admin* will return results for administrator, administration, administer, administered, etc.
A near operator is an AND operator where you can control the distance between the words. You can vary the distance the near operation uses by adding a forward slash and number (between 0-99) such as strawberries NEAR/10 "whipped cream", which means the strawberries must exist within 10 words of "whipped cream".
