Acoustics/Sound

Brand Sounds (10-14-22)

Motoki and co-workers analyzed the impressions created by the sound of brand names.  They learned that “Phonetic elements of brand names can convey a range of specific meanings. . . . The presence of higher-frequency sounds (front vowels, fricative, and voiceless consonants) in brand names tends to be associated with concepts linked to higher evaluation and lower potency, whereas lower-frequency sounds (back vowels, stop, and voiced consonants) tend to be more strongly associated with concepts linked to lower evaluation and higher potency.”

Baby Talking (10-05-22)

Cox and colleagues’ recently published research on constancies found in baby talk regardless of language being spoken raises interesting questions about cross cultural sound experiences.  The researchers share that “When speaking to infants, adults often produce speech that differs systematically from that directed to other adults. To quantify the acoustic properties of this speech style across a wide variety of languages and cultures, we extracted results from empirical studies on the acoustic features of infant-directed speech.

Benefits of Natural Soundscapes (08-15-22)

New research confirms the value of listening to natural soundscapes.  In a recent study “EEG and Heart Rate data were recorded from 10 participants within an [real-world] office in London.  Each participant listened to a Moodsonic Soundscape (lapping lake waves) . . . and typical office sounds while they performed a series of tasks; Stroop Test (cognition), Alternative Uses Test (creativity).  . . . Comparative measures were taken from the typical office sounds and Moodsonic soundscape conditions to compare states of relaxation, engagement, creativity and speed of correct completion.

Managing Open-Plan Office Noise (08-12-22)

Research by Mueller and colleagues confirms the challenges of managing noise in open-plan offices.  They share that “Office workers lately use active noise-cancelling (ANC) headphones to improve the acoustic situation by blocking unwanted sound. . . . Two studies were conducted to examine if ANC headphones improve cognitive performance and the subjective well-being of employees in an open-plan office. . . .

Concert Hall Color (07-21-22)

Chen and Cabrera set out to better understand how color influences experiences in concert halls using virtual reality depictions of concert halls; select surfaces were one color or another, depending on the test condition.  They report that study participants rated “loudness, reverberance, and their visual and auditory preference for multiple virtual reality scenes of a concert hall with various colors and with a music excerpt of various levels of gain and reverberation time.

Sounds and Eating (06-09-22)

Peng-Li and colleagues studied how sound influences food eaten.  They report that “Soft nature sounds [ocean waves] and loud restaurant noises [chattering and tableware noises] were employed to induce emotional relaxation and arousal respectively. One hundred and one healthy university students completed a repeated-measure design of the LFPQ [Leeds Food Preference Questionnaire]; once with each soundscape playing in the background. . . . nature sounds increased explicit liking of healthy (vs.

Impulsive Sound and Performance (06-01-22)

Radun and colleagues investigated the effects of impulsive sound on cognitive performance.  They report that “Exposure to impulsive sound (65 dB LAeq) was compared with quiet sound (35 dB LAeq) and steady-state sound (65 dB LAeq). . . . Compared to quiet sound, impulsive sound caused more annoyance, workload, and lack of energy, raised cortisol concentrations, reduced systolic blood pressure, and decreased accuracy. . . . Compared with steady-state sound, impulsive sound was experienced as more annoying and causing a higher workload and more lack of energy.

Sad Sounds (04-19-22)

Zeloni and Pavani report on sounds that humans link to sadness.  They share that “In Western music and in music of other cultures, minor chords, modes and intervals evoke sadness. . . . we asked expert musicians to transcribe into music scores spontaneous vocalizations of pre-verbal infants to test the hypothesis that melodic intervals that evoke sadness in music (i.e., minor 2nd) are more represented in cry compared to neutral utterances. Results showed that the unison, major 2nd, minor 2nd, major 3rd, minor 3rd, perfect 4th and perfect 5th are all represented in infant vocalizations.
