Blackhole audio8/5/2023 ![]() ![]() The /əʊ/ sound is most often produced by the letter ‘o’, although there are also many words with ‘oa’ and ‘ow’. However, in American English, the ‘r’ is pronounced in these words: ‘part,’ ‘hard,’ ‘car,’ ‘dark’. In these words, the ‘r’ is not pronounced: ‘part’, ‘hard’, ‘car’, ‘dark’. Also, in British English, this vowel sound is often produced by the letters ‘ar’. For example: ‘after’, ‘asked’, ‘France’, or ‘bath’. Many words which have the long /aː/ sound in British English have an /æ/ sound in American English. Specifically, it’s much more common in British English. The /aː/ sound is very different in British and American English. Next, let’s look at the five long vowel sounds. Sometimes, the letters ‘ou’ together can make an /ʊ/ sound, though this is less common. The /ʊ/ sound can be produced by a letter ‘u’ by itself, but also by ‘oo’. Other possible spellings are ‘ou’ and ‘oo’. However, there are also many words where a letter ‘o’ produces the /ʌ/ sound in a stressed syllable. The /ʌ/ sound can be produced by a letter ‘u’ by itself. In American English, the /ɒ/ sound is pronounced with the mouth slightly more open and relaxed, and the sound is more nasal. In British English, the sound is pronounced with the mouth more closed, and it’s usually shorter. The /ɒ/ sound is also different in American and British English. ![]() A few other spellings are possible, like ‘a’ in some words. The /ɒ/ sound is often produced by a letter ‘o’ by itself.

The radar-like scan around the image allows you to hear waves emitted in different directions. Another way to put this is that they are being heard 144 quadrillion and 288 quadrillion times higher than their original frequency. The signals were then resynthesized into the range of human hearing by scaling them upward by 57 and 58 octaves above their true pitch. The sound waves were extracted in radial directions, that is, outwards from the center. In this new sonification of Perseus, the sound waves astronomers previously identified were extracted and made audible for the first time. A galaxy cluster, on the other hand, has copious amounts of gas that envelop the hundreds or even thousands of galaxies within it, providing a medium for the sound waves to travel. ![]() The popular misconception that there is no sound in space originates with the fact that most of space is essentially a vacuum, providing no medium for sound waves to propagate through. In some ways, this sonification is unlike any other done before ( 1, 2, 3, 4) because it revisits the actual sound waves discovered in data from NASA’s Chandra X-ray Observatory. This new sonification – that is, the translation of astronomical data into sound – is being released for NASA’s Black Hole Week this year. ![]() Now a new sonification brings more notes to this black hole sound machine. This is because astronomers discovered that pressure waves sent out by the black hole caused ripples in the cluster’s hot gas that could be translated into a note – one that humans cannot hear some 57 octaves below middle C. Since 2003, the black hole at the center of the Perseus galaxy cluster has been associated with sound. ![]()
